Percussion for all of my scores turned into MS Basic.

Hey. I was using Musescore 4 to compose my work, when all of a sudden I noticed that the percussion sounded off. I was confused, because everything was perfectly normal just a second ago. I checked in the mixer, and it turns out that every single percussion instrument had turned into MS Basic. I looked in MuseHub, and my Muse Sounds percussion pack had somehow uninstalled itself. When I reset my computer and opened musescore, the percussion sound files were back, but every single percussion instrument in every single one of my files is now MS basic. I now have to go to every single one of them to revert this.

I just want to know how this happened.

I use a MacOS M1 on Ventura 13.2.1.
