Hello @DarioFlaman, please add PROTON_LOG=1 %command% to the game's launch options and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.)
I don't play Genshin Impact or using the SteamDeck but I think you may want to try umu-launcher or faugus-launcher. I have been playing Zenless Zone Zero using them and it works pretty well.
I have managed to run Genshin via Steam in the past. As mentioned previously your Proton Logs would be very helpful
This appears to have regressed further, now the main game no longer opens at all. Logs collected from pc running vanilla arch and cosmic desktop through faugus-launcher + Proton-GE Latest, however behaviour is the same on KDE or through Lutris.

Compatibility Report
System Information
I confirm:
Symptoms
Game launches normally via HoYoPlay on Steam Deck.
Login succeeds.
After tapping the door and finishing world loading, the game immediately disconnects.
Current error message:
"Data Error. Please log in again. Error Code: 10010-4001"
Earlier behavior showed:
"You have been disconnected.
Abnormal activity detected on your device's operating environment.
Error Code: 10310-4001"
Issue began after a recent update. The same setup worked previously for months.
Reproduction
Zenless Zone Zero works normally on the same device and launcher.
Issue appears specific to Genshin Impact.
