Hello, My name is Jesse. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

Unfortunately there's been a lot of threads on this issue within the last week. While there isn't a permanent fix, a few people have provided some workarounds worth giving a shot.

When the error code shows up, do not cancel it, just press ans hold the power button until the device turns off. Then press the power button again and turn the device on and check of that helps.
