after my ubuntu was updated to 20.04 shortly, my Zeus + Posidon game, which i used to play via steam running on wine, is not starting any more. There is just a black screen.
I start the steam via:
wine ~/.PlayOnLinux/wineprefix/Steam/drive_c/Program\ Files/Steam/steam.exe -no-browser +open steam://open/minigameslist
which outputs:
ILocalize::AddFile() failed to load file "public/steambootstrapper_english.txt".

Looks like steam didn't shutdown cleanly, scheduling immediate update check

and starts steam as usual. When trying to start the game, i get a black screen only, sometimes even not able to Alt+Tab so i have to restart.
What can i do to diagnose the problem and get Zeus to run again?
