RS Keybord shortcuts became nonfunctional after VS update

After running a Visual Studio 2022 pro update, my ReSharper keyboard shortcuts no longer function. I went through assigning "Tools | Options  | Environment | Keyboard | ReSharper (Visual Studio)" to no avail.  I tried mapping specific keypresses.  I tried doing a Repair Installation in "Add Remove Programs".  I checked "Extensions | ReSharper | Tools | Options | Environment | Shortcut Scheme" is set to Visual Studio and "Visual Studio Commands" has "Override Visual Studio refactorings" checked.  In the course of my misadventures, When prompted to override VS keyboard shortcuts with ReSharper's I accepted "Use ReSharper command" and checked  "Apply to all".

Basically, whenever I am set to use Resharper shortcuts don't work, e.g., Ctrl-T does nothing, Ctrl-Shift-T displays a rather error "The operation could not be completed. Not implemented."

I will try yet another reboot and hope that someone has more of a clue than I.
