My computer (W10 Pro 20H2) is showing the same problem. About a dozen Warnings in the CBS log each time I run sfc /scannow. They are the same folders Try3 listed in his post. Example of mine below:...

Turning Chat "off" did not work for me. Hope it works for others. Sure is an annoying problem.

This started happening regularly in the last couple of weeks on my W10 computer when I try to close GMail. It is annoying, but I have no idea how critical the situation may be.

Great thread. Just what I have been looking for during the last week. Works on my W10 Pro v. 1809 just fine.
