kernel update RPMs call new-kernel-pkg which in turn call grubby, but
none of that stuff ever touches any installed bootloader code. The
only thing modified is the grub.cfg. I don't know how/why, but it's
possible the modification of the grub.cfg is actually corrupting it
but then GRUB should complain if it can't parse grub.cfg

Sounds like this is a computer with BIOS firmware. On BIOS, Fedora
puts grub.cfg at /boot/grub2/, and on UEFI it's at
/boot/efi/EFI/fedora/.
