I've read and looked around for similar cases. I've recently reformatted and its still happening. I got my first crash during a cutscene after about a month of playing Endwalker, then again during another cutscene a week or two later. I've looked into event viewer and saw something related to windows media player at the time.

My screen will go black and my pc will freeze but audio continues to play even voice chat until I reboot. I have an rx-480 (which is known for black screens but flickers for a second) and an i5 6500 with 16gb ram.

Now I'm getting this problem during savage raids. For circle 1 I had to tone everything down from max to low and it seems certain attacks trigger it particularly the purple gem. For circle 2, I've yet to have a problem.
No other game causes this. I haven't gotten any driver failure notifications. I'm trying to narrow it down from HDD to PSU? I don't play with overlays.
