For all 3 of you who read this the fix may be this….
Apparently the way to fix this may be as followa
Boot Windows into Safe Mode or the Windows Recovery Environment
Navigate to the C:\Windows\System32\drivers\CrowdStrike directory
Locate the file matching “C-00000291*.sys”, and delete it.
Boot the host normally.
Also reverting to a previous working setup may be of help
