Trial of the Sekhemas - First attempt crash no matter what

Hi,

Posting since I'm at a complete loss. I know this isn't a new bug and there are multiple posts about the same or similar issues, but I have tried every solution proposed and nothing works.

My game has been working mostly flawlesly forever. Minimal freezes sometimes but never crashes. Been playing since launch, but multiple characters and being a casual player means I just brought my first character to the Trials of the Sekhemas.

The moment I enter the first stage of the trial, no matter what I do my game crashes after 3-5 seconds.

I've tried DX12, DX11, Vulkan. Clearing shader cache. Lowering all graphic settings, using all downscalers, using no downscaler...

I don't know what to do anymore. People are telling me to "move on" from that content but I was excited to try it. Is there any fix I haven't tried?

If anybody is interested: I thought of trying on a different computer but I didn't have one available. Then I thought of GeForce Now - just the free tier. Voila, I'm able to do Sekhema runs using their computers. I don't get it, since I have a 4070 and my PC is technically superior to those from the free tier... but it worked so here's a workaround for those who might need it.
