Wemod cannot start or find open game

I was playing command and conquer Red alert 3 and the game was starting and wemod was working just fine but today it is giving me an error. I click launch and it sees the game and everything but when I tried to start the cheats I didn’t hear the little ding so I alt and tabbed out of the game only to see an error message saying “we are having trouble starting or finding your open game”

I can hit the start game button again but none of the cheats will activate and then it crashes the game. It was working before just fine but now it is screwing up. Does anyone have any idea?
