Build Server Error

Hi, I build a server and gives me this error about postprocessmaterial.uasset

Im using UE4-11.2

Download UE4 source in Github and setup.exe( It download the latest version 12.5 )
I followed the tutorials in youtube

The package is working no error the server only :frowning:

Tried creating new blank project but still gives me the error I’ll try re-download my UE4 Source

Same error…even redownload the source did not help.
Help me pls me I can’t proceed until I resolve this problem.
Everything I did will be on waste if I’m stuck with this error :frowning:
