Musescore kills sound

Expected: Instrument sound plays back in scores
Actual: Loud, long decay distortion plays, playhead is stuck on beat 1

Whenever I launch Musescore, it cuts audio from all sources on my computer. If any score is played, the playhead gets stuck on the first beat and plays a super distorted, crushed, almost granular sound that cannot be stopped. Previously, it output no sound at all, but I was able to get it to at least put out distorted sound, which sets this error apart from existing reports.

How to replicate:
Launch Musescore
play any sound from any instrument

Important to note I was not getting this issue in any previous versions, and if I remember correctly this did not occur even after I updated to my current version (3.3.4.9066 rev 7684abe). This also occurs in 3.4 beta (3.4.0.9337 rev 684f74e).
