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.
All I did: Add installer as Steam Game. Press play to install. Add launcher as Steam Game. Press play to open the b.net client and install w/e game you intend to. In both cases also force use of proton experimental or else it won’t start.
That’s exactly what I did, and it starting the launcher and installing Diablo 4 also worked once in Desktop mode but when I switch back to gaming mode and try launch it there it’s not working.
