I am going to take one of my failing Gigabyte machines and try x64 version of 22H2 (it fails with x86)
I'm also going to try both x86 and x64 without my hidden tools partition.
It's only a hunch, but most manufactures (Lenovo, Dell, HP...) put a hidden partition in place to "Factory Wipe" the device and restore... It's the one thing in common with most of us and possibly this coupled with the changes and problems Microsoft is having with Secure boot has something to do with our partition tables.
Also - MS posted an article on how to disable Secure boot... this test might help some of us
