As the datasheet you reference shows the mcu to have gpio's up to 47, although not stating that, the board must be using a RP2 B-version, not an RP2350(A). You may want to explicit in that.

Thank you for the comment, it has been specified as such in the soldered_nula_max_rp2350.h file with:
#define PICO_RP2350A 0 // 1 for RP2350A, 0 for RP2350B
Is there somewhere else i should also categorize it as such?

I am not specifically knowledgeable in this domain. However, when I look at the RP2040/RP2350 download page, select (as an example) the RP230B Core model, I can see that in its definitions, in the file board.json, RP2350B is explicitly mentioned. Btw: I commented on your initiative as I was appealed by the specs of the board.
