Did you put a Debian Live ISO onto a USB stick ?
If not USB stick: What else stores the live ISO ?
Which ISO image did you download ? (Exact URL please.)

The EFI partition of debian-live-12.0.0-amd64-standard.iso looks like
there is the microsoft-signed shim in /EFI/boot/bootx64.efi . So it
seems at least to strive for Secure Boot compliance.
Maybe it is about SBAT, which can revoke the signatures of buggy shims.
A few months ago such a revocation happened. If your computer saw a
younger operating system, especially one from Microsoft, then it might
have decided to put your Live ISO's shim on the list of revoked
signatures. See for example
https://askubuntu.com/questions/1523438
Consider to ask at mailing list
debian-live@lists.debian.org
which is in charge for problems around building Live ISOs. Maybe the
people there know about Secure Boot problems with recent Live ISOs.
Have a nice day :)
