In case anybody was looking I traced the problem to the QWIIC connector on the Breakout board. I added pins to the board and the used a QWIIC connector to dupont wires - I connected the duponts on the breakout board and attached them to the stemma/qwiic connectors on the RP2040/TMM/T4.1 and then it started working. Strange
