Unfortunately I cannot reproduce this anymore after the install in non-UEFI mode succeeded.
Do you mean that you do not want to destroy your successful installation
or all later installations in UEFI mode succeeded ?
It looks like the EFI partition was not formatted properly.
I identified a few use cases which may cause this failure and are
dependent on the previous partitioning layout, that is why history
matters. Do you remember which partitions the disk had before your first
failed installation attempt in EFI mode ?
Which partitioning method did you use in both cases: manual/guided,
using entire disk/largest free space, with LVM... ?
First attempt: guided, entire disk, LVM+Crypt and full random overwrite.
I guess it was in UEFI mode ?
Next attempts: guided, entire disk, no LVM.
In UEFI or legacy mode ? Which ones failed or succeeded ?
What happens if you take Ventoy out of the equation and just copy the
netinst iso on your USB stick instead?
Both methods work now.
I'm available if you want to try other things to reproduce
