Musescore keeps blowing up my audio.

To preface, I'm a beginner just getting into music production, but I've been using Musescore as a composition software for years now. Recently, I downloaded a DAW, being the free trial to FL Studio 20. Still learning and working out the kinks for the program, but anyways- after using that program, I found it impossible to play any means of audio from Musescore without it loudly making some airy sound from my computer's right microphone channel (like the sound a pc makes when it's overheating but my computer is not hot at all). It seems to grow louder with my master volume and vice versa, but effectively my right microphone is acting busted. This ends up making all of my audio sound busted. FL Studio cracks, YouTube cracks, even short soundbits like discord notifications make the sound. I can fix my general audio by going into settings and running a speakers test, but once I open Musescore again the problem continues to reset. I've tried shutting down my computer, restarting it, doing the setting's sound test while Musescore is open (which ends up turning off the audio playback from Musescore entirely), and even factory resetting Musescore to restore all of its default settings. I was wondering if it might've had something to do with an audio setting that maybe got jacked up. Alas, nothing worked, and here I am sitting, worrying about an upcoming deadline for a project as nothing works.

I think it could be one of three things-
Musescore being weird and giving my computer issues (since the problem only seems to occur when I open it)
My computer's speakers being weird- but I doubt it, because they have never given me problems beforehand and seem to work perfectly fine when remedying the issue (unless Musescore is opened, of course)
Or FL Studio 20 being finicky. I don't know though, because any audio from that seems to work perfectly fine. The problem first started after I closed the program once and then went into Musescore.

I have no idea what's happening and how to fix it! This is my last hope! If anyone has any suggestions I would appreciate it!
