I have two old legacy PC's which were recently kicked out of insider program, but both of those get this CU.
My Raspberry Pi 4B was happily running Dev until it was kicked out, then Beta until now,
it got kicked out again after installing this update. 😢

edit: I'm going to try clean installing again, but this time offline to avoid the CU and see what happens
I thought Eddie said they have tighten the restrictions with latest changes this week.
Something else looks unusual in you picture, I don't remember seeing the watermarks on 22000.xxx, I see those only on Dev 22xxx.1000 ?
