Challenge
If McAfee FS minifilter MFEHIDK driver is loaded into Windows kernel, then it doesn’t allow any other driver to load at lower altitudes, it only allows other drivers to load at higher altitudes, supposedly because of proactive defense logic of McAfee Antivirus.
Therefore Veeam CBT driver cannot track changes on CSV and backups/replicas are in crash consistent state.

Solution
Please uninstall McAfee Antivirus from all production Hyper-V nodes
More information
Driver function FltAttachVolume returns error 0xC00000BB when mfehidk mini-filter driver is loaded/installed.
VeeamFCT mini-filter driver can’t load at lower altitude(201900) and cannot attach to CSV volume.
McAfee PER/BUG number is 37418
