I'm afraid I don't see how reinstall could change anything here.
Although I also didn't see how, and I, at first, refused to follow the suggestion of clean installation (in this forum, BTW ), I finally did it. There was no other solution, and this workaround was the only actual suggestion.
I don't know why, but it helped, immediately. I can't guarantee that this will work for the OP too. I only wrote from my own experience.
