Mine started when I upgraded from Win 10 21H2 to Win 10 22H2 on the 19th. I too think it is from that.
No, it is not! Mine started at the beginning of August under W 10 21H2. So, it has nothing to do with the upgrade to 22H2, which was a minor one anyway.
I concur. Mine started in August as well after a regular Windows update. I was on W11 21H2.
