Sticky incorrect IndentationError

[99991]

Type: Bug

Behaviour

I get sticky IndentationErrors that do not go away, even if all code in the file is deleted.

Sometimes, the hover menu for the error does not open, so it might also apply to other kinds of errors.

Note that there are only two lines in this file, yet the error is supposedly in line 151 or 152.

Steps to reproduce:

I could not yet find a pattern. Started happening a few weeks or maybe months ago.

I don't know, but I have not encountered the bug in the last few days, so it has probably been fixed by some update in the meantime. Thank you for asking though!
