Help with Error Message on my computer

This morning, I performed a system restore, but it went wrong. So, I had to ask a local technician for help. He was very professional and saved me from the brink of a blue screen!

I reinstalled the Windows 11, and all programs, applications and games were restored. Everything returned to normal and I'm very happy.

The only problem I'm currently facing is that every time the computer shuts down and restarts, a screenshot prompt appears, showing a warning message about a real-time update error. I have no idea what this is related to, but as long as I click "OK", the computer can run normally.

Do you have any ideas? What is this related to? I have cleared the DNS, reset the router, and restarted it five times, but still see this prompt.
