Struggling to install Bazzite

question

So I'm attempting to install Bazzite AMD on this Dell laptop (Ryzen 5600 series CPU, int Radeon graphics). However, I can't get the ISO to boot from the USB. When I try it takes ages on a Dell logo screen with Bazzite at the bottom and a spinning load icon. Then I get the error in the screenshot.

FYI I am using a Ventoy formatted usb as I have quite a lot of ISOs on this USB drive
