Issues with Musescore Update

Hi! I recently (very recently) just updated to musescore 4.2, and suddenly it is like everything crashed and stopped working. Everything is super delayed and often after inputting a few notes, I have to wait a few minutes because my screen is stuck. I also cannot upload any scores to musescore like I used to. It says "it is uploaded", but the score has been forever loading for hours now and will not show on my account page. Does anyone know how to fix this? I also tried deleting the installation and redownloading it!
