The fourth Baldur's Gate 3 hotfix went live on Steam earlier today, a smaller update than the previous three but one that still promised to fix a number of problems with "crashes, bugs, flow issues, and companions who keep trying to sleep in."
Unfortunately, it apparently caused new crashes, too, so Larian has rolled it back. If you saved your game during the brief period when Hotfix 4 was live, you won't be able to load those save files until the hotfix is re-published, which Larian says it'll do as soon as it fixes the crashes.
