Windows has ALWAYS been tweaked for Intel first. Now that may be because of secret deals in back rooms, or just because it's the original CPU architecture that the Windows kernel was written for, or because the MS programmers are more familiar with Intel CPU idiosyncrasies... Or probably a mix of all of the above.
Win10 didn't play nice with AMD CPUs originally either, but it was eventually sorted out. AMD uses some unique and proprietary techniques in their CPUs, and MS has to code 'shims' into the kernel and drivers to handle it, because the base kernel and drivers are written for Intel. A lot of the OS testing is done on VMs and... surprise, VMs emulate Intel hardware.
It's embarrassing for MS, and another sign of their poor focus on coding for updates, and stupid reliance on the Windows Insider program for beta testing, instead of testing in house. And of course, most Insiders are testing Win11 on... Wait for it! VMs that emulate Intel hardware.
They will fix this. It's not that big a deal. No one should really be installing Win11 unless they understand that they will actually be free beta testers for the next year. AMD users, like me, should definitely hold off. I know people want the new and shiny OS, but Win10 is a solid OS right now that's not due for end of support for four years, so there's really no rush.
Be smart. Don't be a first adopter unless you actually want to help MS for free (and that's cool), and don't be surprised if the shit hits the fan a few times in the coming year. Backup your data.
