Thanks for the reply.
At first the scanning would stop between 40-50% depending on the thrash or residue need to be cleaned.It does differ. So what I did to delete some of the residue from the system files was to scan my system files C: then cancel it. When there is ample files/thrash already scanned and I will delete it thinking it would do the trick. However, it doesn’t as of current system ninja 3.2.1 would stop at 80%-90% and would star crashing. And at different times at 33% when using 3.1.7 or 9300 plus files were scanned when i reinstalled 3.2.1.
