I had a similar experience playing it a few months ago—I bought it on steam so it had all the patches, but I got stuck on this one mission where it would refuse to spawn the entrance to the next part of the quest. I spent a few hours googling trying to figure out what was going on, and then I gave up. It’s such a beautiful game, and has a lot of potential, but it is definitely not as stable as any other major AAA game I’ve played in the last 10 years. I would also get random crashes if I enabled raytracing (despite having an RTX card).
