Issues updating BIOS for 5700x3d

SOLVED - I had an NVME SSD still attached to the board - removing it seems to have sorted everything out.

Hi,

I'm having issues updating my BIOS to run the 5700X3D.

Currently I have a 2700x in the PC with a GA-AB350-Gaming motherboard.

Downloaded the F31 bios update and installed via Q-flash, which seemed to go fine.

But now when it boots my keyboard isn't working on the BIOS menu - so I can't select Q-flash to update to F41 > F51g. A probably related issue that I also can't solve is that it now boots straight to BIOS and I can't get it to boot to windows - I've seen elsewhere that a BIOS update can mess with the boot order, but since I can't access any options for boot order in the BIOS I'm stuck.

Any help trying to figure out how to get my keyboard working would be great.

So far I have:

\-Tried other USB ports on the rear plate (2.0 / 3.0 /3.1)

\-Tried a second keyboard (also tried it in other ports)

\-Resetting CMOS (shorting the pins on the board and separately removing the CMOS battery)
