Not strange at all.

I'm not familiar with GRUB anymore, but it sounds like perhaps the file
bootmgfw.efi has not been signed with a key that is trusted by your board's
SecureBoot feature. Hence, booting with SB enabled causes a load failure
while booting without SB fixes the problem.

Like I said, not familiar with GRUB, so not sure if that file is grub's
problem or not. Just a pointer to something for you to investigate.

Thanks,
