Charger (genuine 87W) was working only on one side of USB C port and there was 5V and sometimes 20V (was charging fine but when connected any USB device was not visible in macOS) but when use other side of charging cable there was nothing on ampmeter.

Replaced CD3215 and both side are working but both stuck at 5V and 0A.

PP3V3RV0_AON in diode mode 0.550V.
CD3250 LDOs diode mode readings are OK.

Where to start?

PP1V1_UPC_XA_LDO_BMC got 0.15V (0.460V in diode mode).
Rest LDOs got correct voltages.

Changed CD3215 and still the same issue - tested with board only (no battery).

You had working machine before replacing CD3215 chip.
If new chip is really good, then bad solders, or knocked off components.

CD3215 batch was faulty :/
Used another CD3215 all works fine now on both sides :)

Thank you very much :)
