Trial of Sekhemas Crashing

So I've done this trial about 15 times at this point, just getting acquainted with the functionality...this is by far the most frustrating experience I've ever dealt with in a game.

2/3 times that I've gotten to the boss fight, I've crashed and have had to restart all over again from the beginning. I'm not doing that again. It also happened to my friend last night. If this is a known issue, at the VERY least make it so that you restart JUST the boss, so the player doesn't have to spend an extra hour redoing the trial because of a game issue.

I'm running a Ryzen 7800x3D with a 4070S with 32GB of ram. And I have fiber internet. Everything on my end is stable, and I even went the extra mile to re-verify my game files, so what's going on?
