All my Heroic installed GOG games don't take controller input anymore

Idk when this started happening. Tried to carry over my cloud save of StrayGods (GOG) earlier, that worked. What didn't was the menu. At first I thought it was the game but then I installed Spelunky (GOG) to test it and that also doesn't take controller anymore. Tried Rocket League (Epic) and that works. Could this be a GOG exclusive issue? Any known fixes?
