Maybe Ventoy has problems with the injection of its own cert with 2023 ISOs? Have you tried any other ISOs via Ventoy that already have the new 2023 cert? If those work, maybe HBS can change something that helps Ventoy. If those don’t work as well, I hope that Ventoy will fix that soon 
*Edit: There’s already a GitHub issue for this, might be related:

Quick follow-up to that Ventoy issue I mentioned.
TLDR: If you're using Ventoy with secure boot, you should update
That GitHub issue raised a small discussion that resulted in some updates to Ventoy yesterday and today.
So now the current version is 1.1.16 and brings a bunch of fixes for the new UEFI CA 2023 certificate.
Btw: Ventoy now also comes with a bypass secure boot feature that is on by default so old ISOs with blocked certs should work, too.
