Catalina Supplemental Update & HD Mounting Fails (Invalid Key Length)

After running a supplemental Catalina update today (10.15.7), I got an error mounting a HFS+-formatted hard drive (com.apple.DiskManagement.disenter error 49244)

First Aid doesn't help at all.

What next?

Mac mini, macOS 10.15
