Endnote invalid pointer message during Word update?

When updating MS Word (Office 365) a message popped up displaying “Endnote invalid pointer”. I don’t remember if there was an option to click on OK or not. Nevertheless, Word updated successfully.
Recently, I had to reconfigure CWYW in Word as it disappeared from Word menu. I recovered it by starting Confugure EndNote.exe and it is working properly now. Does the message above has anything to do with CWYW in Word?
I am on EndNote 21.2 and Windows 11 24H2 x64.
