there is persistent setting in UICR register NFCPINS that must have its lowest bit cleared. Run this
peek32(0x1000120c).toString(16);to see if it all FFs or there is zero or FE.When this is OK then still those pins are not the same as any other. Check this note , there is increased leakage between them so they affect each other.
