Hello y’all, I’m at my wits end. I got the GoG version of BG3 (cause DRM free yay!), but for the love of me I cannot get it to work. I’ve done so much googling and so many workarounds, I’ve installed .net, I’ve skipped the launcher, I’ve used the alternate .exe, I’ve tried proton experimental and 8 and hotfix, but nothing has got me even as far as a loading screen. I just get a flash of black then crashed back to desktop. If anyone has any insights or help I would greatly appreciate it, I’m using Heroic right now but honestly I’ll do whatever to get this thing working.
It broke for me because gustav.pak was missing. Might be the sameissuee for you or something similar. Try repairing the game with Heroic. If that doesn’t work (didn’t for me because of space), try downloading it on a different PC and copy the files on top. That fixed it for me.
Also, disclaimer that this just worked for me and I can’t guarantee anything.
