I found the why thus error happens. It’s all because of Substance Plugin. I just deleted it and game laucned succesful.

Thank you so much. That was my issue as well. I would have never figured that out lol

No problem, mate.

After 2 days of searching this answer worked.

Can you tell me how to find this Substance plugin?

How do i find this substance plugin?

First of all, open the Epic Games Launcher. Then, click on the library. You should see your Unreal Engine versions. Under your latest installed Unreal Engine version, you should see “Installed Plugins.”. And then, just uninstal substance plugin by clicking delete button.

thank you!!! :smiley:

but what if we want to use Substance plugin for materials? if you delete it then you cannot use the materials when packaging… is there a way to resolve this so i can use the substance materials and package it?
