Broken pipe error but not because FFMPEG, in stead `permission denied`

I have been working with MANIM quite some time now and it all worked well. I haven’t worked on it for about two weeks and all of the sudden (with no serious changes on either manim or computer) I run into an error when I try to compile a video.

I get the following:

PS C:\Users\steve\OneDrive\Documenten\Nerds\Manim\manim> py -m manim .\example_scenes.py SquareToCircle -pl
Media will be written to ./media\. You can change this behavior with the --media_dir flag.

BrokenPipeError: [Errno 32] Broken pipe

Now I have found other issues regarding the Broken Pipe issue, but as far as I can tell, this was always because of the FFMPEG codec. But in the above we find:

1/15 [00:00<00:02, 5.89it/s]C:\Users\steve\OneDrive\Documenten\Nerds\Manim\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\00000_temp.mp4: Permission denied

As if this map is unreachable. I already tried to change the MEDIA DIR, but same error occurs. Also, when I render an image, so use -ps, no error occurs at all.

Any thoughts?

It was the antivirus, thanks for the encouragement, its fixed now

I am having exactly the same issue but I am not sure I have any AV. I am on macOS Catalina. Any ideas?

Might be ransomware protection (on your OS I think the default protection is XProtect). You could try a project folder outside of your “home” folder. While this isn’t a permanent solution, if this works then at least manim’s install is probably okay.

In my experience, ransomware blocking has been less informative, but it’s getting better. A few weeks ago ffmpeg just died on me with no explanation; today I got an alert and was prompted to allow ffmpeg access to my protected folders (and now it works like it should).

edit: Also…apply updates for everything; something over the last few weeks may have fixed it for me today.
