after entering main game, after 10 seconds of completely normal gameplay (opening packs, starting a match etc), then it crashes blank without any error message i can locate. (wine log & lutris log both completely normal. )
wine log completely normal (no new log) at crash. only clue is ‘compiling shaders’ at bottom left corner before crashing but i guess that’s intended.
system is pop!os 22.04, running lutris battlenet installer then Hearthstone.
Maybe try other runners - Is there a reason you switched away from the default wine-ge-8-26? If you are also using Steam+ULWGL, Proton - Experimental tends to work for me a lot more regularly than 9.0
I have not played anything on Battle net since Diablo 3, but that still works without issues, and playing 20+ mins of Hearthstone tutorial levels works fine using the wine-ge-8-26 runner.
Last thing is that the reddit link has people running it through bottles, which is also going to be pulling a WINE runner - see if you can track down what WINE that is using?
