Unable to complete/start an autoinstall using d-i/preseed on Focal 20.04 desktop

[XaTriX]

Well it seems related to debian-installer, idk.
This report is regarding the desktop version.

I cannot launch an auto install, using a .seed file correctly formatted (i guess and also use somes already validated) on /cdrom/ or "url="

Tried a lot of combinations about boot options : severity=critical only or maybe-ubiquity, addressing locale or using auto, auto=true, etc.

Can you reproduce this ?

Or can you manage to launch an auto install of a Desktop version ?

Note : testing inside a virtual machine using up-to-date VirtualBox on a Fedora 32 desktop also up-to-date.
