After renaming open file, attempting to save another file with the previous name results in error and poor Ux

Problem Description

What steps will reproduce the problem?

Renamed file that was open (let's call it "A.py") in Finder to "B.py" and then tried saving a new file from Spyder with the same name ("A.py"). Then, Spyder gave warnings that the file "A.py" is not found and asks for me to close it. Then it got stuck in an infinite loop. But, in the end, the new file was saved as "untitled.py".

I am using windows 10, I believe I cannot reproduce this issue.
