Immovable large folder installed
During installation MuseScore 4 sets up the 13.4GB folder
C:\ProgramData\MuseHub\Downloads\instruments
When running MuseScore 4 appears to rely on this folder being present, as without it
the Mixer Sound buttons only give access to SoundFont sources.
However, there seems to be no way to move this very large folder to any other location.
The folder does not appear in Edit>Preferences>General>Folders. It is not mentioned
in Diagnostic>System>Show paths.

Try uninstalling it via Muse Hub.

Thanks Shoichi; the comment was most helpful. I eventually managed to get MuseHub to install the large folder elsewhere and for Musescore 4 to then use it.
I think the location of this folder should be accessible within MuseScore 4 under Edit>Preferences>General>Folders
as are SoundFonts and VST3
