I have the same problem and actually tried to reset cryotools and set back UMA back to 1gb. Still no luck.
The only real difference I see is forcing experimental or hotfix. That atleast gets me to the Nvidia logo. Else it’s crash to homescreen directly.
I see that the game creates 2 crash logs and a crash dump in its Bin home folder when crashing. Sadly no easy helpful informations in there.
Found something else yesterday after rabbitholing down the steam forums. Now you solved your problem already. But hopefully that keeps it from coming back.
Currently there seems the a problem with PowerTools installed and the Game.
So if the game is crashing after the Nvidia logo (on experimental or hotfix) try to remove PowerTools and restart the Steamdeck.
