I’ve managed to chroot (a very dumb word) thru a LiveUSB session, with the following commands:
It's better not to call things dumb without understanding. It's short

dnf reinstall grub2-efi grub2-efi-modules shim
That seems to work? Downloads and seems to install without any errors.
The next step though;
grub2-mkconfig -o /boot/grub2/grub.cfg
fails with the following:
/usr/sbin/grub2-probe: error: failed to get canonical path of ‘/dev/mapper/fedora_crypt’
I have no idea what that means.
What does "ls -l /dev/mapper/fedora_crypt" show?
On the side, I also sees that despite the grub reinstall, theres no vmlinuz or initramfs kernel files in the reconstructed /boot partition, so I tried running
grub has nothing directly to do with those files.
dracut --regenerate-all
which results in
dracut: Can’t write to /boot/efi/[long-ass id code string]/[kernel version]: Directory /boot/efi/[long-ass id code string]/[kernel version] does not exist or is not accessible.
This is true - that folder isn’t in /boot/efi. But I dont remember ever seeing it there, and just to check I did a fresh test install on another drive and theres nothing like that there either.
That's one of the possible places for it to write the files. Did it
find the right place? If not, you'll have to specify the file yourself.
"rpm -q kernel-core"
e.g. kernel-core-5.18.13-200.fc36.x86_64
"dracut /boot/initramfs-5.18.13-200.fc36.x86_64.img 5.18.13-200.fc36.x86_64"
You will also have to re-install the kernel-core package to the vmlinuz
file installed.
At this point, it might just be easier to do a backup and re-install.
