[BUG] - [LINUX] - "Other" store platform causes app to hang when selecting game

[rofocalus]

Describe the bug When selecting "other" for platform, rather than "steam", "epic games", etc, the application hangs and throws exception. Tested with "Voices of the Void", Among Us, Outward. This was seen on Arch Linux, other reports show it occurs on other Linux distros.

To Reproduce Steps to reproduce the behavior:

1. Open r2modman
2. Click on Voices of the Void, or any game that has "other" option for platform
3. Application will hang before calling function for next screen, application will work as expected on same game if "steam" is selected for platform.

Expected behavior Ability to select executable for game, on "other" platform.

Screenshots Unable at the moment :(

This must indeed be a problem with the AppImage version because I'm having the same problem months later

I am also seeing this bug on the steam deck running steamos(linux) and using the appimage build. I'm trying to select Inscryption installed from gog.com by selecting platform "Other" in r2modman
