Backup has failed with this rather vague error multiple times. Any suggest as to where to start?
It seems like a WMI query which is trying to get details about your machine's disks is failing here.
If you open Run > msinfo32 and then browse to Components > Storage > Drives and Disks. Does that bring up any information?
Also, can you attach the Failed operation log file which can be found in the below path please?
