That is well old enough to be vulnerable to Spectre and Meltdown. But again, I have no idea if this is the actual reason. I am simply assuming that if the cause and/or solution was easy, it would have been addressed by now, by the community. To be so common, yet have no real leads... that's the best I can do.

I don't want to bury the lead. For security reasons, Microsoft may not allow older processors to connect to their Playfab service because they are vulnerable to certain classes of side-channel exploits. All Intel CPUs up to I think the 9th gen, and all ryzen through the 2000 series are vulnerable to this side channel attack, and did not have access to the mitigations deployed for them. Intel 10th Gen and beyond and Ryzen 3000, 5000 and 7000 are fine, unless I'm misremembering what generations were affected.

Spectre or Meltdown, right? I'm no expert, haven't internalized the differences, just have vague memories of those having something to do with what you described.

Those are the vulnerabilities. I mostly forgot, but I think they're essentially the same mechanism, with different ways to exploit. However both are side channel attacks (essentially forcing memory to dump protected out). These vulnerabilities will become especially dangerous as AI becomes more ubiquitous since you'll be able to train AI tools to simultaneously attack a target, and then sort through the volumes of trash data for the good things, like normally hash protected information.
