0.06 is too low.
Check again 15-20s after power is removed.

I tried to replace all cd3217 with a good board but now all the usbc ports turn on and off, before only UG400 did it, 3V8 AON IN DIODE MODE AND 0.160 LDO OBVIOUSLY TURN ON AND OFF

Did you respect the position in the board for CD3217 chips?
Compare diode mode readings on their LDOs with good board.

Yes I put them in the same position I compared the readings ldo the diode mode with a working card and it's regular, I even reassembled the replaced cd3217 on another card and it works normally

Check for knocked off, or other damage caused in the replacement process.
