cant get to installer

yesterday i tried to install monterey on a mac pro from 2012 (macpro5,1) to an empty ssd running mojave on an hdd with oclp. everything went fine until the first install part, where it gets to 13 minutes left, goes up to 21, goes down quickly and in minute 14 it freezes crashing the computer and making it reboot. i thought it finished installing but when it rebooted back in oclp boot picker there was still the usb installer "install macos monterey" and not the "macos installer" which is the second part of the install.

a day later, i formatted the usb and downloaded sonoma instead of monterey and made the usb. when tried to install this time it did almost the same as in monterey. i tried everything: trying again, changing usb port, removing hdd with mojave, resetting nvram, etc. i cant seem to get this working, im not an expert in doing opencore installs so idk if this is maybe dumb but any help will be appreciated. ill put a video showing what happens.
