It was tested and no problem found.

Look in the ifw.log for the VSS error code (presuming it's still enabled - if not, enable it), and see https://www.terabyteunlimited.com/kb/kb ... on-failed/

KB5124010 is a Preview update.

Unless you have a pressing issue that it fixes, I would suggest uninstalling it.

You could also use PHYlock instead.
