In my log you can saw .
Set to voltage raw 1800, step by step. -> You must measure PSU output voltage 18V +-
Set to voltage raw 2000, step by step. -> You must measure PSU output voltage 20V +-

And here is photo where measure output voltage on PSU

If you have a multimeter you can measure impedance(Ohm) on Chain0 between Source and Drain and Gate ( MOS transistor)
And give us result.

Here is photo what to do.

And you can try measure impedance between V_Boost and Input Voltage -> on the Chain 0

thank you for your reply i done as you suggested and attached photos in quote please check them
