Would you be willing to produce a crash dump that we could analyze?
If so, download this https://learn.microsoft.com/sysinternals/downloads/procdump
From an admin elevated command prompt from where you placed procdump, run
procdump -e -ma Path\To\LaunchBox\Core\LaunchBox.exe
Then go and make LaunchBox crash - that should create a file from wherever you ran procdump from - then, using your favorite secure file sharing service, send us a link to support@ email or through our bug report system at https://feedback.launchbox.gg/
I'm not confident we'll see anything useful, but without any other errors from your machine, I'm hopeful 🤞
(let me know if you need any help with the above steps / command)
