I am no expert but...
it is in a boot loop that keeps going back to the 'Set Up' screen not sure what it is called but no option to boot into windows.
This menu has no restore options end clicking 'Exit Setup' just reboots back to the same screen.
Booting from USB and trying the Windows image from their support site does not work.
I think that is technically what we call a brick or is there another option?
I would really try to contact support. Perhaps they can point out some sort of key combination that triggers a different way of booting. Otherwise @sharpuser can perhaps point you in the right direction. I think he lives in a different time zone, so it may take a while
I have had a similar problem with one of my Surface Book 2 devices. And I could not boot from USB.
But then, I created a new USB image from the other Surface Book using media creation tool. That worked. Was able to install clean, then OneDrive restored my files. I only had to reinstall programs (Office & 3rd party desktop). At one point I had to enter the bitlock key, which was on my Microsoft account under “Devices”.
I have not been able to figure out why my first USB stick did not work. The second was a new, cheap, 8GB stick, and worked perfectly.
