Macro keyboard shortcuts not working in new macro template document

Stefan_Blom Yes, I am saving my macros to the Normal template--at least I think that is the case. I am creating the keyboard shortcuts using a  macro like this:

'CreateBookShortcuts
'Assigns convenient shortcut keys to the book macros
Sub CreateBookShortcuts()
    CustomizationContext = NormalTemplate
    KeyBindings.Add _
           KeyCode:=BuildKeyCode(wdKeyControl, wdKeyShift, wdKeyH), _
           KeyCategory:=wdKeyCategoryCommand, _
           Command:="FormatHTMLTag"
    KeyBindings.Add _
           KeyCode:=BuildKeyCode(wdKeyControl, wdKeyShift, wdKeyP), _
           KeyCategory:=wdKeyCategoryCommand, _
           Command:="FormatCSSProp"
    KeyBindings.Add _
           KeyCode:=BuildKeyCode(wdKeyControl, wdKeyShift, wdKeyV), _
           KeyCategory:=wdKeyCategoryCommand, _
           Command:="FormatCSSVal"

This macro is part of a module `BookMacros` that lives in the Normal' template's 'Modules' folder. When I inspect keystroke shortcuts through File->Options->Customize Ribbon, I see that the keystroke shortcuts I have defined do indeed show up:

Keystroke shortcut exists, but doesn't work!

However, the keystroke shortcuts do NOT work!! The only way I can get them to run is to manually run them from the Developer->Macros dialog.

This is really strange. These shortcuts worked fine previous to my recent transition to Windows 11.

Thanks in advance for any help you can provide. 

Note: I have tried "Reset Macros..." and then re-running the macro to redefine the keystroke shortcuts. However, that didn't work.
