I updated to the latest LaunchBox version (13.21), but unfortunately, the issue persists. To troubleshoot, I tried the following commands: C:\Users\visse\LaunchBox>procdump -e -ma C:\Users\visse\LaunchBox\launchbox.exe C:\Users\visse\LaunchBox>procdump64 -e -ma C:\Users\visse\LaunchBox\LaunchBox.exe C:\Users\visse\LaunchBox>procdump64 -e -ma C:\Users\visse\LaunchBox\Core\LaunchBox.exe C:\Users\visse\LaunchBox>I:\Downloads\Procdump\procdump64.exe -e -ma C:\Users\visse\LaunchBox\launchbox.exe Each time, I received the following error message: ProcDump v11.0 - Sysinternals process dump utility Copyright (C) 2009-2022 Mark Russinovich and Andrew Richards Sysinternals - www.sysinternals.com No process matching the specified name can be found. Try elevating the command prompt or using PsExec to make one as SYSTEM. psexec.exe -s -d -i cmd.exe procdump.exe -accepteula ... However, using the process ID (PID) instead worked successfully: I:\Downloads\Procdump\procdump64.exe -e -ma 22368 This created a dump file: LaunchBox.exe_250425_104025.dmp (size: 3.5 GB) I uploaded the dump file to the topic I previously created on the LaunchBox Feedback page, titled: "Crash to desktop when adding game or media.

Thanks for moving my question to its own topic. I’ve already tried those solutions, including the commands mentioned here: Use the System File Checker tool to repair missing or corrupted system files. Yesterday, I reinstalled Windows 11 over the current version while keeping all my data and apps. Starting completely from scratch would be way too much work, so I chose this approach. However, the issue persists. It seems to be related to Launchbox, as everything works on version 13.18, but not on later versions. Perhaps it’s the combination of factors. Also, why am I the only one experiencing this?

OS: My issue started with the implementation of .NET 9.0. Until version 13.18, I didn’t have any problems, but from 13.19 to 13.21 beta 3, the same issue persists. Everything works perfectly in Launchbox, except when I have to browse for a location while adding a game. For example, when inserting media or selecting the ROM/executable file of a game: the folder opens, but instantly, the BCOD (Blue Circle of Death) appears. And after a few seconds, I’m back at the desktop. In the Event Viewer, I see this, but I don’t know what it means: Toepassingsnaam met fout: LaunchBox.exe, versie: 13.21.0.3, tijdstempel: 0x67d30000 Naam van foutmodule: ntdll.dll, versie: 10.0.26100.3775, tijdstempel: 0x5e4be250 Uitzonderingscode: 0xc0000409 Foutoffset: 0x000000000011e216 Foutproces-id: 0x47A8 Begintijd van foutieve toepassing: 0x1DBB36EA560323E Faulting-toepassingspad: C:\Users\visse\LaunchBox\Core\LaunchBox.exe Faulting-modulepad: C:\WINDOWS\SYSTEM32\ntdll.dll Rapport-id: ad6df754-dc37-4cde-953a-4e8204d9c261 Faulting-pakket volledige naam: Faulting-pakket-relatieve toepassings-id: - System - Provider [ Name] Application Error [ Guid] {a0e9b465-b939-57d7-b27d-95d8e925ff57} EventID 1000 Version 0 Level 2 Task 100 Opcode 0 Keywords 0x8000000000000000 - TimeCreated [ SystemTime] 2025-04-22T10:10:07.2458190Z EventRecordID 27317 Correlation - Execution [ ProcessID] 25140 [ ThreadID] 25396 Channel Application Computer GAMEPCDAVE2023 - Security [ UserID] S-1-5-21-157999631-2574045945-3901820913-1001 - EventData AppName LaunchBox.exe AppVersion 13.21.0.3 AppTimeStamp 67d30000 ModuleName ntdll.dll ModuleVersion 10.0.26100.3775 ModuleTimeStamp 5e4be250 ExceptionCode c0000409 FaultingOffset 000000000011e216 ProcessId 0x47a8 ProcessCreationTime 0x1dbb36ea560323e AppPath C:\Users\visse\LaunchBox\Core\LaunchBox.exe ModulePath C:\WINDOWS\SYSTEM32\ntdll.dll IntegratorReportId ad6df754-dc37-4cde-953a-4e8204d9c261 PackageFullName PackageRelativeAppId Co-Pilot says the following about this event: "Based on the details, it looks like the error originates from ntdll.dll, which is a core Windows system file. The exception code 0xc0000409 often indicates a stack buffer overrun, meaning that something—potentially LaunchBox or a related dependency—is causing Windows to terminate the process for security reasons." The strange thing is that it doesn’t always happen, sometimes I can add media or ROMs without crashing, but most of the time, I can’t. I already downgraded back to 13.18, and everything works fine, but when I update to the latest version, the issue returns. I also reported a bug, but I hope someone else has encountered the same issue, which is why I’m posting it here too. Additionally, I’ve already tried reinstalling Launchbox in a different location, but that didn’t solve the problem either.

I'm still facing issues with adding games or media in LB. The problem is inconsistent—sometimes it works fine, but other times it crashes to the desktop without any warning. Everything worked perfectly in version 13.18, but the issues began with 13.19 and persist in 13.20 and even in the 13.21 beta. The crash typically occurs when I click "Add Image" while editing a game or browse for a game’s executable. The explorer window opens, and after a few seconds, the program crashes back to the desktop. I can restart LB and occasionally manage to edit the game while browsing for media or the executable. However, the crash might occur again, making it very frustrating. I've already submitted a bug report but was hoping to find out if anyone else is experiencing this issue. If someone has encountered this and found a solution, I’d greatly appreciate your help.

Same problem here. Logged out of Emumovies and logged in again. That works. But with the same creds I can't connect to Emumovies in LB. edit: just saw this post on Emumovies: So changed my password and everything works again!

Ok thnx I opened a topic under Report a Bug.

Until 13.18, there were no problems, but with 13.19, after the .dll file issues, it started crashing when adding games. I can click on Add, the Window opens to select the file but then I already see it, the blue circle and gone is Launchbox. I was hoping for 13.20 soon, and that was the case, but still the same problem. No log files, because it crashes to the desktop without error. So back to 13.18......and hoping for a 13.21 or 14.0

I installed multiple times 13.19 and back to 13.18 and still have all my settings.

I went back to 13.18 and wait for the 13.20 update. My 13.19 was working after de deletion of the file and folder, but I had multiple random crashes without error message.

After removing the plugin ScummVM.dll my Launchbox was starting but I have a lot of crashes without error message. It happens when I want to add a new game or when adding media. It freezes for a moment and then back to desktop. So now back to 13.18 and it works as it should. I'll wait for a 13.19 beta x update or 13.20 or 14.0 Or any suggestions?

Thnx for the fix. After that, I was curious if the ScummVM plugin needs to be repaired. It looked okay, but to be sure, I clicked on repair and now it's pending. Closed the Plugin Manager window and: After the restart of Launchbox, it looked the same. So probably it was okay in the first place, but because I removed the .dll and the folder, I wanted to be sure. Edit: I've been playing around for a while now and I've had multiple crashes when adding a new game or adding new media.

Can you re-upload this file?
