Build fails immediately

Its unable to load the AutomationTool file for some reason. Here’s the log. Sorry if one bit isn’t in english, I don’t know why.

This is quite literally the full log, from when I press " package mod " to Build failed.

I am posting this here because I cannot get help from the game developers that made the dev kit.
