Processing OneDrive finished with warning: Cannot complete this action

Case # 07871930

I've been seeing this for about a week now. The warning message isn't all that helpful. Any ideas how to fix this?

We are seeing it across multiple clients, across OneDrive, Teams and SharePoint. We've seen it rise in frequency for about 3 weeks.
It can be resolved by finding and deleting the file, but we just had a team with 160+k item failures, so that's not really viable.

Support has told me RnD is looking into it.
