This is looks like a schematic https://i.imgur.com/EpE4dGj.jpg LDO power regulator is nice - 40uA current. ME6211-3.3 datasheet CP2102 is powered by LDO and don't turns off, i think.. Okey, buy 60mA is very-very high current.

Maybe you need to turn off some ESP32 pins? I see, that you don't turn off Wi-Fi.

Look: https://www.hackster.io/nickthegreek82/esp32-deep-sleep-tutorial-4398a7 "When the ESP32 is in active mode, it draws around 60mAs of current from the battery." wow FireBeetle ESP32 IOT 10uA out of the box

I also want to get 10uA in my project, so find all area info.

Thanks for the hints! Still interested (had no time to follow up).
