Error while uploading crash report

After scanning a piece, there are several places that need correction. I get to one spot where there are extra time and key signatures where it is not suppose to change, but only in some staffs. When I delete either one of them, the program crashes and I get the MuseScore Crash Reporter window as happens sometimes. But now, when I enter the actions when the crash occurred and try to send the report, I get Error "Error while uploading crash report; Host requires authentication." I tried first rebooting, and then removing MuseScore and re-installing." Does anyone know how I can fix this? Note - it started right after installing the latest update. Thank you.
