I have recently upgraded my SSD in the Steam Deck to a 1TB one and created a 300GB Windows partition on it to be able to play Genshin Impact. So far so good, that is working as it should.

Before upgrading I had the 64GB model and used a 512GB SD card. On that I had Diablo 4 installed and it was working perfectly fine. But now I’m unable to get it to work again. I can’t remember which Proton version I used but pretty much any version I tried (including GE-Proton ones) is not working now that I’m trying to install and run Diablo 4 on the new 1TB SSD.

Did anyone else experience something like that?

Edit: As long as I’m in Desktop Mode I can add the “Battle.net Launcher.exe” to Steam and launch it with Proton Experimental and I’m able to install Diablo 4 but as soon as I go back to Gaming Mode the Battle.net launcher isn’t starting anymore.

    Did you reinstall SteamOS or just clone it to the new SSD? I’ve seen people say if you don’t reinstall the OS properly when upgrading it can cause some issues but I’m not sure if those situations apply to what’s happening here
