nothing works, gets "NameError: name 'func' is not defined"

Any command fails with same error, I tried different examples and different files, as well as uninstalling and reinstalling moviepy and decorator, nothing worked. VideoFileClip is created and can be accessed, but it fails when methods are called. See below a minimalistic example from frame extraction example:

Expected Behavior

Extract a frame (or equivalent command to perform any operation on file).

Actual Behavior

from moviepy.editor import AudioFileClip, VideoFileClip
video = VideoFileClip(r"D:\dati\ordine\programmazione\youtube\salmon.mp4")

video.save_frame('prova.jpg')  #this fails with error shown above

I don’t know if this was really what solved the issue, because it was a delayed effect at restart and it was not the only thing I had tried, but maybe it was removing and reinstalling, as indicated at the end of this thread: https://github.com/Zulko/moviepy/issues/1625#issuecomment-973056577

pip uninstall moviepy decorator
pip install moviepy

I’m closing this for now as OP solved their problem but we don’t know what the fix (or actual issue) was, so there’s nothing to go on with regard to labelling the issue.
