cooking error ( failed to cook module 7a8a1659-491a-1cee-9e51-499853d3782a )

Summary

Hello,

For 1 week now I can’t launch a session, every time I try to launch a session, my character is killed and I get the following error

PlatformCook : Error: We made a mistake in preparing this content.
PlatformCook : Error : errors.com.epicgames.content-service. cook_failure
PlatformCook : Error : CookJobId :64aac3cb-9454-4049-b8a1-05dd7de790e6
PlatformCook : Error: An error occurred while communicating with the game servers (failed to cook module 7a8a1659-491a-1cee-9e51-499853d3782a (artifact 9581f60f-4a54-4b0c-92b6-e96af1affd14:pc) (cookJobId 64aac3cb-9454-4049-b8a1-05dd7de790e6) with error.

So I used the revision control to go back to an old version, everything works fine, I can launch the game etc … but every time I make a change to the map that requires “push changes”, the error keeps coming back (even for a simple change).

For example, I’ve simply moved a floor and the error comes back…

Can you click on the 3 dots next to Launch Session and in the menu select Validate Project, it will take a little while, but lets see if that gives any useful information.
