We experienced this on a machine that had just installed some updates. The cause was the dependent Base Filtering Engine service hanging when trying to start.

1. Fix the BFE Service Registry Keys:
   Windows 7  |  Windows 8  |  Windows 10  | Windows 11
   
2. HKLM\SYSTEM\CurrentControlSet\Services\BFE\Parameters\Policy
   Change the permissions on the Policy key
   Add NT SERVICE\BFE
   Advanced permissions – Allow:
   - Query Value
   - Set Value
   - Create Subkey
   - Enumerate Subkeys
   - Notify
3. Select Replace all child object permissions with inheritable permissions from this object
4. Restarting Windows may be required

If still not good, try resetting the BFE service permissions / security descriptors in an elevated command prompt.
