Steam Deck GDI+ Error (Decisive Campaigns Ardennes Offensive)

[Domisan]

Please help me out with this error, i really would love to play on the Steam Deck.

Game is starting, i can play but as soon as i click on Preferences ingame, i get the following error:

„unhandled exception has occured in your application...\n\nA null reference or invalid value was found [GDI+ status: InvalidParameter“

Thank you very much!

These games are not supported on steam deck. Though I know some ppl got shadow empire running on it nonetheless by installing some extra 3rd party stuff. So I guess in theory it is possible.
