Incorrect Playback Speed and Rhythms

For some reason musescore keeps playing the wrong rhythms for my piece. Everything sounded fine a few days ago, but now some parts will play faster/slower than others at certain sections and some parts do a completely different rhythm than what I have notated. I’ve looked through and adjusted literally everything I could think of and restarted my computer multiple times to no avail. Does anyone know how to fix this?? I’ve added the score but I don’t think it’ll make a difference because I’m sure it’s just my computer, but please let me know if something can be done.
