Hello there @SimaFans!
From your provided log, it seems the main error is “Failed to find command Turnkey”, meaning that the whole packing process is failing due UE not being able to find or execute the Turnkey command. Your engine installation is mostly likely corrupt, or missing components.
So, the first step is to verify your install. In the Epic Games Launcher, navigate to your UE build, then click on the dropdown arrow next to it and select “Verify.” This will epair any missing or corrupted files. If the issue persists after the process, I would suggest a full reinstallation.
The next step to check on your local setup, is to make sure that all elements related to VS and the SDK have the correct version for your UE version. You can check that following the doc below:
Finally, perform a clear cache of your project, via deleting Intermediate
, Saved
, and .vs
folders from your main directory. After that, regenerate your project files from VS. Hope this helps!
