I get the following error:
Traceback (most recent call last):
File "C:\pinokio\api\wan.git\app\shared\utils\audio_video.py", line 173, in combine_and_concatenate_video_with_audio_tracks

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

hopefully this is just a misconfiguration of my environment.
