Did you uncheck every flag at the Initial Setup stage?
Maybe related:

Qubes 4.1 installation failure

Did you changed template selection earlier during installation (here)? If not, something went wrong at that stage, can you search for “qubes-template” in /var/log/anaconda and share logs that you find this way?
