Have tried disabling autostart ?

After a fresh install Stuck on a bootloop after qubes loading screen

Did you have any errors during Initial Setup? Try to boot with disabled qubes autostart: Maybe your sys-net/sys-usb is failing to start because of a PCI device attached to them. Also at this screen: You can press Esc key to show the log and check at what point is it stuck.
