Update not working

I am trying to update musescore but its not letting me. Im not sure if its a bug from my computer or from the app. I am stuck on version 4.3.0, the updates have worked up until this one. I showed some photos of what pops up when I try to update. I would try and completely uninstall musescore but I dont know if this error would pop up when re-installing it then I cant use it at all. Is there a way I can fix this?
