STM32L432KC Nucleo GPIOA resets to 0xABFF FFEF instead of 0xABFF FFFF

STM32L432KC Nucleo GPIOA resets to 0xABFF FFEF instead of 0xABFF FFFF

I can't write 0 to $4800 0000 [GPIOA_MODER]

Ports B and C behave as expected: the correct reset values and it is possible to write 0x0000 0000 to B and C.

How can I resolve this?

Or has GPIOA died?

Firmware version: V2J45M31

ST-LINK/V2-1
