GOG.com - Jagged Alliance 2

I am running the game on MacOS Catalina 10.15.6 with the JA2 1.12 revision (latest available on GOG)

The game starts fine but I am experiencing random crashes and frequently enough thats its not fun to play the game.

I am completely new to PlayOnMac but I would love to contribute in helping troubleshooting and fixing the issue.

I see there is a debug button but I have no idea what I'm doing lol

Downloaded PlayonLinux using the terminal in Fedora 26. All associated dependencies downloaded successfully. Installs ok, but gives an error at the end. Says it has completed, but the program JA2 keeps crashing before running. Downloaded the PC JA2 installer direct from GOG. 

 

Here is the error:
