You can stop the program, but for this I don't think a sfc /scannow would resolve but a chkdsk /f may be desirable to check the condition of your HDD.
After the chkdsk has completed and machine rebooted, open Event Viewer and when it has read the data, expand Windows Logs - click on Application/Action/Find and type chkdsk into the Find box and press enter.
Cancel the Find box and read the report in the scrollable pane below.
You are looking to see if it reports any KBs in Bad sectors.
If it does then I would advise immediately creating a system image and the means to recover from it in preparation for a full HDD failure.
If that comes back clean, I think I would go for a repair install for this but as your USB ports don't work, you will need to create a Win 10 install disk.
A repair install won't affect personal stuff or installed programs.
I would use one of your other machines to do this.
Follow the instructions at

This will start the process which could take a few hours - it took ~7¼hrs when I tried it on one of my Win 10 1903 laptops.
