Why do I get the warning "Warning: Name is nonexistent or not a directory: C:\Users\<​myusername​>\AppData\​Local\Temp​\Editor_ey​pjt" when opening Matlab, and how to fix it?

Lately I have been getting the warning message "Warning: Name is nonexistent or not a directory: C:\Users\<myusername>\AppData\Local\Temp\Editor_eypjt" when opening Matlab 2020b. When going to "C:\Users\<myusername>\AppData\Local\Temp" the folder "Editor_eypjt" does not exist. There are folders with similar names though, that all contain one matlab script with only a single semicolon in it. This warning appeared one time earlier, after switching the version to 2020b several weeks ago, and has happened this week again. I am not aware of any changes that I did in the meantime that would cause this folder to disappear again.

Can this cause any trouble for Matlab running properly, and how can I resolve this issue?

As this is a folder in the %temp% directory, Matlab has no guarantee that any file will remain available. So I doubt this could cause any issue. If it would, that would be a bug you should report.
