Animation saving crashes the program

[JoonasD6]

I tried many different parameters (only touching the values of 'save_video', 'plot_reverse', 'fourier_N', 'animation_time' and 'n_eval') with custom images and then I ran into a problem when I set save_video to 'True'. No video was saved (I checked the whole project directory and no text.mp4 was found with my contents), and when closing the animation window -- regardless of original svg (as I tried with the original unmodified parameters again) -- I get this in terminal:

950 of 1000 pointers calculated.

Calculation of data points from coefficients done.

Animation object created.

Begin saving the video.

So something goes wrong saving the video. I made sure latest ffmpeg is installedjust in case, noticing that is used for the video (although it was not in the readme instructions). Running fresh Python 3.10.1 on Windows 11 (both Python and ffmpeg isntalled via Chocolatey with default settings, then imported all packages mentioned in the readme with pip in order for the program to run).

Interestingly, the exact same code (same files, render settings, source image) does run on my MacBook Pro (Mid 2015) running MacOS 12.0.1 and Python 3.9.9. No idea why the video saving works there but on my Windows laptop.

Unfortunately, I also have no idea what the problem might be here. I wrote and tested the code on my Windows 10 (64bit with Python 3 and Matplotlib "3.3.2", installed with Anaconda) computer. However, I also have a "Windows on Arm64 device" running Windows 11, or Windows 11 for beta testers a few months ago. The 32bit emulation for Python has a lot of bugs for me and doesn't always work as intended (I notice it especially with Numpy, Scipy and Matplotlib as I use those the most). Until now I always thought it was because of the 32bit emulation, but maybe the problem is Windows 11.
Nevertheless, I would suspect it's because Matplotlib doesn't get along with Windows 11, or at least didn't a few months ago...
