Respected Roxana:
Firstly, I was using PSP( GGA/PBE) from quantum espresso https://www.quantum-espresso.org/pseudopotentials. Then I wanted to try LDA/Norm conserving But I didn't get these from this QE address. So, I have created PSP from the atomistic module of QE. But the error remains the same.

Most Respected Roxana;
I was using QE 6.3 and EPW 4.1 but now I have installed Quantum ESPRESSO 6.4 and EPW 5.1 but the error remains exit.
