Who has put first the entry number 3? It can not boot, it contains an ancient BOOTX64.EFI.
Your UEFI BIOS probably did that. When the first choice fails to boot, it uses that as a fallback. You can manually update that by copying the "shim.efi" from your main boot to replace the "BOOTX64.EFI". You may also need to copy "fallback.efi" and "MokManager.efi". Or remove "fallback.efi" from that directory and copy "grub.efi", "MokManager.efi" and "grub.cfg" from the main boot. If booting is failing because of the recent kernel update, then you willl need to boot the previous kernel.
