Hey Eenkalzet,

I ended up reaching out directly to SE through a ticket submission. A friend recommended I try that as well since he has had great interactions through that. They had me try everything in your list except checking the sound driver and a few other unlisted items. Sadly none of those worked and I believe that 2021 sound driver is going to be tied into a piece of Sennheiser hardware they aren't updating anymore.
The story doesn't end happy because I was trying some final things like dynamic resolution and after another crash my PC wouldn't boot. It ended with having to run the PC through integrated graphics and no GPU plugged in. Something with my GPU is fried at this point so I'm trying to make use of the warranty on it.
At the end of the day, I believe this is an issue specifically with my GPU, I believe it to be faulty. I'll be logging back in with a new GPU here in a couple days hoping that cutscene and the duty run flawless.
Appreciate the reply and support!
