Factory Reset your telemetry with OOSU: O&O ShutUp10++: Free antispy tool for Windows 10 and 11
I had made a post yesterday in a couple different threads about this issue and it worked for a few. https://www.halowaypoint.com/en-us/forums/85d779d52cfd46918b4f8b638f2e3c7b/topics/several-achievements-not-unlocking/b3f908eb-d239-4285-9334-84e9b162c96a/posts?page=1#post14
Currently if you don’t want all telemetry data being collected after you factory reset you can turn off Cortana and OneDrive stuff. I have not had the time to go through everything else telemetry wise though and figure out what’s causing the stat/achievements to be blocked. So if anyone figures out the rest, feel free to post it.
