I have no idea if this new symptom is related to the earlier/previous
lock/freeze issue. I connected a year old 5 TB ext. USB HDD to AUSKEY
hub to do a Time Machine back up into its encrypted APFS partition. It
prompted me its password and failed so I had to re-enter it (used the
touchbar's unlock button instead of enter key and mouse click), and then
it never mounted. I tried to force mount it in macOS Big Sur v11.6.2's
Disk Utilty app, but nothing. Not even an error.

I ran First Aid on the drive and its partitions (also have exFAT and old
macOS extended journal (HFS+). No isssues. I disconnected and
reconnected the drive for APFS partition. No password prompt this time
even though the other Time Machine drive/partition did which was fine. I
told Disk Utility to mount that same APFS drive/partition and then
finally got an error -- "Could not mount ???APFS (Encrypted) Black Seagate
HD???. (com.apple.DiskManagement.disenter error 49218.)". That's not good.

So, I decided to unplug the HDD with all drives unmounted again and
rebooted. The shut down took like a minute and then finally rebooted by
itself. I logged in and retried the external USB HDD with its APFS
drive/partition. It worked fine this time. Hmm, weird/odd. I'm seeing
lots of random (weir/od)ness these days! :(

Closing and reopening lid, and disconnecting and reconnecting external powered USB devices didn't help at all. I even tried to reproduce this hard lock ups from what I remember. I doubt it is temperature related since it had been in the 60-70 degrees(F) indoor from the outdoor cold weather and rain. Right now, I'm running Disk Utility app's first aid to see if its internal 2 TB SSD is OK.
