amazing how you figured this out and Larian is sitting there drooling
TBH, I didn't figure that much out. Just went around the web, asking for folks' opinions/help who are much more knowledgeable than myself on these matters. And then I simply started to read what my PC was reporting...

What I will say though is that, at least on my PC, this seems to prove that the launcher is indeed what's messing things up for folks. I just played BG3 for at least 5 hours straight and... nothing. Still got a clean Reliability Report as well. I haven't checked it, but I bet if I re-enabled the launcher, the crashes would come back.
I also talked to a buddy of mine telling him about all this and he said he never had any sort of crashes... though he was on vacation for the last 2 weeks or so, so he might have simply not played the game with that Aug 25th patch applied. In any case, since most of the people with crashes whose reports I found on the web were on Intel-systems (at least the ones I read who did mention their specs), I asked my buddy for his and he is on an AMD-system.
No idea if this has any significance, just thought I'd share it.
The advice to try running the game directly from the exe has been around for weeks.
Yes, I found that advice pretty early on as well ... however: Only using that launch-option that I ended up using seems to truly shut off the launcher. Using the "--bypass - launcher" command-line did not help in my case.
Besides: I think it's not too much to ask that this sort of thing gets ironed out. Especially since we're talking about a, IMO, rather pointless feature like a dedicated game-launcher you don't need to launch the game.
