I crash constantly in any Shavronne instance

I cannot progress past act 8.

I crashed continuously in act 4 when fighting Shavronne just before the act 4 boss too but managed to kill her even through the multiple crashes little by little before the crash to windows.

In act 8 I cannot since I crash in her little map area before getting to her.

I have a RTX 3080 (Driver 580.97 updated Aug 12 2025_
MS Windows 10 Pro
AMD Ryzen 9 5900 X 12 core
32gig RAM

I have changed the resolutions, frames rates, directX settings and vulcan all multiple times.

I have had this problem only since this league. It was not as bad earlier in the league.

Not I cannot progress past act 8.

Please help
