The first thing I did after turning on my deck the first time was look up and follow online instructions to get the epic launcher to work on the steam deck. I couldn't tell you now what I did, but I didn't have any great difficulty following the instructions. The epic launcher opens. I can play the games I have through Epic just fine. The only problem I have is instead of closing the epic launcher normally I have to force close it. I have yet to set up Xbox PC game pass. I don't know if a work around for that has been found yet.
