WD Unlocker not available in latest Windows 10 - cannot access encrypted WD Passport Ultra

I have been successfully using WD Passport Ultra drives with activated hardware encryption on my Windows 10 machine. After plugging in the drives, the WD Unlocker executable became available in the File Explorer as a separate drive. Unlocking the drives with the password made them available for regular business.

Today I tried all my WD Passport Ultra drives … to no avail. The drives are not recognized in a way that the WD Unlocker mechanism becomes available. I cannot unlock and, thereby, access the drives.

Disk Management reports that I “…must initialize a disk before I can access it.”

Does anyone know, if anything has been updated in Windows 10 that no longer allows WD encrypted drives to be accessed??
