Sounds like memory corruption, unfortunately it's one of the hardest things to diagnose. Traditional memory tests with 64GB of DDR5 are unlikely to find anything, from what you described your system is so unstable that you should be able to find a simple reproducible scenario that just fails. For example, I've had more success with using COD Warzone as a memory test than any other tool out there.
Here's what I'd do. Make sure your BIOS is up to date (also, what's the mobo? is it QVL RAM?). Run your RAM at 4800, with Gear 4 (or whatever the 1:4 mode is called) and increase your VccSA just in case. If you have PCIe Gen 5, use gen 3/4 instead. Disable fTPM. Start with a fresh Windows install. Disable Windows VBS and subfeatures such as memory integrity. If that doesn't help, I'd try a different motherboard if I can. If not, different RAM. Only then would I blame the CPU itself.
