TypeError: arrays to stack must be passed as a "sequence" type such as list or tuple.

Installed with pipx over Pop!_OS 22.04 LTS:

pipx install jumpcutter                                                                                                      
  installed package jumpcutter 0.1.6, installed using Python 3.10.12
  These apps are now globally available                                                                                                                                                       
    - jumpcutter                            
done! ✨ 🌟 ✨

And tried exactly the same way on an Ubuntu 20.04 (working fine). Tried with webm and mp4 with identical results:

jumpcutter --input 'my_video.webm' --output 'my_video_(without_silence).webm'

Running with the arguments:
Namespace(input=PosixPath('my_video.webm'), output=PosixPath('my_video_(without_silence).webm'), cut='silent', magnitude_threshold_ratio=0.02, duration_threshold=0.5, failure_tolerance_ratio=0.1, space_on_edges=0.1, silence_part_speed=None, min_loud_part_duration=-1, codec=None, bitrate=None)

I'm having the same issue on Win 10, trying with mkv and mp4 files. But I installed with pip.

Running this command from prompt: jumpcutter --input testfile2.mp4 --output outputfile2.mp4

Running with the arguments:
Namespace(input=WindowsPath('testfile2.mp4'), output=WindowsPath('outputfile2.mp4'), cut='silent', magnitude_threshold_ratio=0.02, duration_threshold=0.5, failure_tolerance_ratio=0.1, space_on_edges=0.1, silence_part_speed=None, min_loud_part_duration=-1, codec=None, bitrate=None)

For me, what fixed it was wrapping list() around self.iter_chunks in the file AudioClip.py within the moviepy package and then manually specifying codec = 'libx264' in the file VideoClip.py for the same package.
