My repairman informed me that AC is not working because TXV is stuck open and resulting in low pressure side pressure higher than high pressure side

I bought new evaporator and TXV and he assembled it

AC worked fine for an hour but resulted in gradual reduction of air flow resulting in zero flow from vent. If I shut off car for few hours then everything would work fine again for an hour

I thought that I made a mistake of not replacing dryer / receiver causing moisture from air causing TXV icing up thus stopping flow

After changing dryer, compressor was found dead not powering up even after direct powering

I have also changed AC control unit on the back side of flow control knob. Still repairman has not been able to fix the issue

All relays are confirmed fine

Am I missing something?

Please advise
