GRUB Reinstallation 2-2-24 to Present

Hi folks,

     I updated my PC, running Debian Testing AKA "Trixie" on Friaday and 
haven't been able to boot into Debian ever since. I can tell that I need 
to reinstall GRUB, but I'm having trouble with the instructions on the 
Debian page for reinstalling GRUB 
<https://wiki.debian.org/GrubEFIReinstall#Using_A_Live_CD.2FUSB_To_Fix_Your_Current_System>. 
It sounds like I'm supposed to do the /efi=runtime/ boot option and also 
mount the EFI variables, but when I try to mount the EFI variables, GRUB 
says it can't do that. What am I supposed to do? How can I fix this?
