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.
