There was another thread on this same topic recently:

Deleted duplicate file

I created a duplicate file to check out a couple scenarios and deleted it once I had the answers I needed.Now I keep getting [Screenshot 2022-03-21 070557] every time I open the file. How do I stop getting this message, as it’s annoying?

Your answer may be in there.
