22.7.0.76 Full System Scan won't complete

Hi I have windows 10 and up until the 22.7.06. update all worked well. But now I cannot get the full scan to complete.

I have shut down the pc more that once, and run live update more than once but still get partway through and it hangs, even end task will not close the scan,  only shutting down the pc and restart.

Thanks guys.
