UPDATE!! as of like. I wanna say the 23rd, ? honestly i don't remember exact day, but I FIXED MY issue. It may be helpful for others! SO somehow i created an utter mess on my desktop between Win updates, drivers, Armoury Crate, and ALL my games. i forgot to mention that my crashes extended to every game on my computer above a certain size back to Skyrim. The key hint was Genshin Impact being unaffected save for repairing files.
I suspect its tied to EAapp/Steam if you're having issues? Possibly?
I'm using a i710700K CPU, 16GB Memory, and a RTX3060, and Plenty of storage, and none of these components are showing any signs of problems outside of Specifically my Games.
What I did, was clear Everything Affected, including launchers. rolled Win update back, drivers back, uninstalled Realtek Audio Driver and Armoury Crate, AND EA and Steam, and all associated games. I did not remove any game save data as that's all stored separately in my Documents, not my Programs on either of my two drives. After everything was cleared, I slowly started redoing the drives and updates, and tested it with Skyrim (Win update caused its crash) and then Veilguard because it took 3 hours to install lol but it WORKED. Runs great, no longer causes huge Memory or CPU spikes, all temps and usage is stable again.
I can't guarantee it will solve everything, but if you're contemplating a full OS reinstall, try this first. Good luck guys!
