Windows Defender scan stops without completing

I can't complete a scan with Windows Defender, it stops after about 2550 files are checked with Defender being switched Off.  I've ran a MRT complete scan which found nothing and sfc /scannow (this found and corrected some errors without changing the problem).  Any suggestions please?
