Have you updated GRUB recently? As I understand things, GRUB is not updated automatically. Once installed, it has to be updated manually. In fact, it is an option upgrade step at <https://docs.fedoraproject.org/en-US/quick-docs/upgrading-fedora-offline/#sect-update-grub-bootloader-on-bios>. And there's the forbidden signature database that blacklists buggy versions of GRUB... <https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/managing_monitoring_and_updating_the_kernel/updating-the-secure-boot-revocation-list_managing-monitoring-and-updating-the-kernel>.
