TypeError: 'MovieWriterRegistry' object is not an iterator

Used the minimal example and getting this error. Any thoughts on how to fix?

The program implements animation in artistanimation, so it should output MP4 format instead of GIF format

I also get the same "TypeError: 'MovieWriterRegistry' object is not an iterator" when attempting to save animations using FuncAnimation. Any help gratefully appreciated

I remember it seems to be caused by the format, but I have forgotten the details, because I rarely use this library at present.
