KeyError when autosaving file

Description

What steps will reproduce the problem?

It’s happened whole I guess it tried to save changes to the file.

Traceback

Yes, but only in the internal file explorer.

I found one possible cause: if you rename a file in the file explorer, then it is automatically renamed in the editor, but the autosave information is not updated. This leads to the KeyError exception posted.

@DeadVampire Do you remember by any chance whether you renamed the file?
