Windows 11 on a Surface Pro 9 suddenly shuts down when asks for account PIN

I was using a USB-C device with HDMI, mouse, keyboard and Ethernet connected to a Surface Pro 9 and powering it thourgh USB-C (it worked well for months).
Now when I load Windows it loads upto the screen when I must insert the PIN to access the account. After 3 seconds it shuts down, so I cannot get inside Windows...
I don't know exactly which version of W11, but I think it's updated...

Going to BIOS is ok, the pc does not shutdown.
I tried a USB-C windows backup made at the beginning of W11 installation months ago: I press troubleshoot and I reach this point

Even this way it does not shutdown, so could it be some driver problems ?
The "startup repair" does nothing...

I can't see here how to load in safe mode with less drivers... Why?
I have no restore points. I think I have one old Macrium backup inside the SSD, but I have no USB boot for it.

Could I use some command prompt / other options?

Thanks for help

1) Find several flash drives that you can format (> or = 8 GB)

2) Find a working Windows computer

3) On the working Windows computer create tools to use on the problematic computer



4) Create a bootable Sea Tools flash drive






5) Create a bootable Windows 11 Media Creation Tool (MCT) (Windows 11 iso)





6) Run the Sea Tools Long Generic test > take pictures > post images or share links

Make sure to detach all external drivers to see anyone causing the problem also check to see if battery faulty by connecting power adapter.
