Installation • Can't chroot into "mnt" to reinstall Grub

I am having an incredibly difficult time trying to fix GRUB. I am running Debian 12 on a Lenovo Yoga 720-15IKB. My partitioning scheme has 3 partitions:
nvme0n1p1;
nvme0n1p2; and,
nvme0n1p3.

nvme0n1p1:
File Format=fat32;
Flagged as “boot”;
Size=512MiB using 7.78MiB;

nvme0n1p2:
File Format=ext2;
No flags;
Size=488MiB using 450.22
Contents:

nvme0n1p3 is encrypted using LUKs and is subdivided into 3 LVMs:
yogadebian—vg-root
yogadebian—vg-swap_1
yogadebian—vg-home

This is basically the LUKS/LVM install option when I installed Debian.I have tried as many of the fixes as I could find, including the Debian GrubEFIReinstall (https://wiki.debian.org/GrubEFIReinstall).

I am able to unencrypt yogadebian-vg and then mount the 3 volumes at “/mnt”, though this is where things break down. I have to “mkdir” for many (not all) of the “/mnt” in order to prepare the “chroot /mnt” command.

The problem seems to be with the efi/efivars. They appear to be missing? I did try Boot Repair but it didn’t fix it.The last Boot Repair analysis I did is at: https://paste.debian.net/hidden/2cf0a60a/

I have never been able to “chroot” so that I can just reinstall Grub. I really do not want to do a clean install of Debian and Grub before I exhaust just reinstalling Grub. I don’t want to go through the ordeal of getting my Root back up to speed. I know I can do that without changing my Home directory.

If anyone has any suggestions on what may be preventing me from being able to chroot I would very much appreciate it. Here are the results of some of the inventory commands:
