Execution of command "{C:/intelfpga/20.1/quartus/../nios2eds/Nios II Command Shell.bat} make all 2>>

Hi,

I am using Quartus Prime Standard 20.1 on Windows 10 . I am trying to get DDR3 uniphy example design generated.

I am getting these errors for Cyclone V as well as Stratix V

Error: Error: mem_if_ddr3_emif_0: Error during execution of script generate_ed.tcl: s0: Error during execution of "{C:/intelfpga/20.1/quartus/../nios2eds/Nios II Command Shell.bat} make all 2>> stderr.txt": child process exited abnormally

I tried to install patches and WSL as given in link below
