Cablecard in Tivo stopped Working - Now no longer Paired

I have a cable card in a Tivo that stopped working Yesterday (Saturday 11-30-2024).  The cable card had been successfully working for a while and I know that the cable card was successfully paired.  The cable card now says that it is no longer paired.  I have tried the cable card self-install authorization and can see the cable card and host id in that system, but I get an error when I try to pair the card.  I spent an hour or so with support - via text (who stopped responding after about 25-30 minutes - not cool) and via phone who while nice, said that there was nothing she could do.  

I am hoping to get help getting my cable card successfully repaired.  I hope I can direct message support and they can get me to someone who can help.  Thank you for any assistance you can provide.
