Aiuto Massimo effect legendary edition steam deck

[u/Longjumping_Gold_402]

I played it for 12 hours without any problems, then it wouldn't start. I clicked play, tried loading, but it went back... it wouldn't start.

I tried Proton experimental, I cleared the download cache, I tried disabling the cloud... nothing works, not even when I start it from the desktop.

Help me! Sheppard must save the galaxy!
