Well, we'll have to wait for more data from the OP won't we? Voltages, board pix, etc. Seems to be par for the course these days. Encourage them to grab the multimeter and use it and all that...
Max current in the MS5611 datasheet is 12.5 mA. From second link I posted, SMD marking on the LDO for that particular board pix is S2PA. A search reveals:

So _one_ clone would not have the MIC5205 as mentioned in the first link I posted, but it might have a MicrOne ME6211. Promises 100 mV dropout at 100 mA load, even better than the cheap XC6206 that I once bought.
The SMD NFET marking is 702, which makes it likely to be a dual 2N7002-type NFET. Well, the thing might switch on via the body diode when Pico side pulls the line low, but it it doesn't look like a hard or fast on and that might be too slow for I2C comms.
So I'll just wait for more data from the OP.
