I'm trying to launch PackFileManager.exe (I'm using 5.2.4) on my Ubuntu 22.04 using mono runtime. At first I was able to launch it and got to main menu, clicking "cancel" for every game when it proposed to choose installation directories. But afterwards I played a bit with the options in the menu, closed the application, and wasn't able to launch it ever since. It produces a "game directory not found" error now and doesn't start. I tried removing downloaded folder, unpacking and launching it again. I also tried purging mono-runtime and mono-complete and reinstalling them. Nothing helps.
