Asok

I was following another post about this same issue, and then stumbled across this one. This fix seems to have fixed my issue as well.

Found another post that had a fix that worked.

I have same problem. Clean install of Windows 11 (23H2) plus a few others things (7-zip, Firefox, Samsung Magician, and Nvidia drivers). Installed LaunchBox 3.8. I get the startup dialog, then the full screen window, and then the "Add Games" dialog. After a few seconds, the "Add Games" dialog disappears on it's own and I can no longer interact with the UI. The app is technically not hung - I can see it pumping messages in Spyxx. It acts like it has a hidden model dialog on top of the UI. I have to kill the app to make it go away.
