tldr: Steam deck freezes and game crashes after the first run of my deployed package build.
I’ve looked around other posts about steam deck crashes and I can’t find any good answer.
I followed the steps recommended to test my game on my steam deck. I am packaging for windows (currently development, tried shipping but same results).
I am uploading the built game to my steamdeck and providing the mygame.exe file.
I set it up to use proton executable and when I run the first time it asked me to install the usual C++ data. On this run, i’m able to run my game just fine.
But after I close it once and try to open the game. I get the splash screen for unreal and then just get a black screen and eventually get the GameThread time out after 120 secs.
Not sure what can be causing this on the second run or any after (even restarting steam deck, etc). If I upload another version of the same packaged build and do the first step, setting up proton etc, it works again.
Any recommendations would be appreciated.
