Immediate crash due to mutagen failing to import

[Quacklick]

Describe the bug
The program is entirely failing to run because it can't import from mutagen.

To Reproduce
Download the 2023-7-24 CLI release and attempt to run it. Any arguments can be added, or none at all, as the issue occurs before anything is processed.

Expected behavior
The program should attempt to download a Twitter Space.

Output

Desktop (please complete the following information):

• OS: Windows 10
• Version: 22H2 (build 19045.3208)
• Installation method: Portable CLI Binary

Additional context
I have tried the following troubleshooting steps:

• Closing all open programs
• Redownloading the binary
• Running the program from an admin shell
• Upgrading, downgrading, uninstalling, and reinstalling Python
• Updating, uninstalling, and reinstalling mutagen
• Placing the binary in various places near or inside a manually-downloaded copy of mutagen
• Restarting my computer many times

Cannot reproduce, try install with pip and make sure your PYTHONPATH environment is set to the Lib directory inside your Python installation.

I have the same problem with the GUI portable release.

$ ./twspace-dl-GUI.exe

No problems when installing CLI version with pip.
