I did submit a bug report months ago, but didn't receive a reply. It was kind of a pain to submit, but I pulled the crash reports, included screenshots, etc. I think this was back in September-ish when the game was still fairly new, so they were probably flooded with reports. Might be worth trying again.
It's definitely not a new issue -- I've been researching this since the first time we hit Act 3 way back in August and seen it posted by others both here and on the Baldur's Gate 3 subreddit, but none of the patch notes or hotfixes that have come since address this issue specifically. My partner and I started playing on launch day and still haven't beaten the game (:
