Failure writing workspace file

Whenever I close MuseScore 3, any score, a message pops up saying "Failed writing workspace file C:\ProgramFiles\MuseScore 3\workspaces\Advanced.workspace" (the words might not be exactly those, as I'm using a Portuguese version). Other than popping up, that message doesn't seem to cause any harm at all, but it is annoying to see it come every time I close MS. Maybe I should reinstall MS3?
