How to avoid main libvlc error when using the python-vlc package?

Question

Every time I use the module and call vlc.MediaPlayer(), I get a long list of error messages printed on the console. The top 20 rows are:

[000002635638b9b0] main libvlc error: stale plugins cache: modified C:\Program Files\VideoLAN\VLC\plugins\access\libaccess_concat_plugin.dll
[000002635638b9b0] main libvlc error: stale plugins cache: modified C:\Program Files\VideoLAN\VLC\plugins\access\libaccess_imem_plugin.dll

[000002635638b9b0] main libvlc error: stale plugins cache: modified C:\Program Files\VideoLAN\VLC\plugins\access\libdshow_plugin.dll

The package version is: 3.0.12118. I use it on a machine with Windows 10.

How can I get rid of this error? Or is there perhaps a better, more stable package to use for playing mp3 files?

Took a lot of searching, but I found this thread from 2018 that actually worked for me. There should be something called vlc-cache-gen.exe in your VLC folder. Run that in a command prompt (as administrator), and pass in the plugins folder as an argument. Instantly fixed it for me:

"C:\Program Files\VideoLAN\VLC\vlc-cache-gen.exe" "C:\Program Files\VideoLAN\VLC\plugins"
