Wow, that looks like a very cool sensor!
That's odd - the boards should be the same. You're using up to date firmware on both? The default I2C clock speed is 50000 (but it could be different on earlier firmwares) - it could be something that trips up the module.
One thing that will get you is that on the Pico, B6 and B7 are used for the Serial console when USB isn't connected - so on initialisation they are set up as a Serial port. I guess they might end up getting pulled low at times and that could confuse the module?
Maybe try something else - B4 and A8 on I2C3, and see if you have any more luck?
