Sorry for the problems. I know we already went over this by email, but for the benefit of other users who find this post: it appears to be some sort of memory corruption based on the information in the dump file.
While there have been a lot of problems with the earlier raptor lake intel processors, I’m not aware of any significant problems with the Core Ultra series right now. It may be worth trying a stress test utility like prime95 and see if that identifies any stability problems with the system.
