This says the Unreal Automation Toole is failing but it is not clear why… Is this the entire Output Log? Typically there’s a “Warning/Error Summary” in the log…
To ensure you get the entire log contents: Open your Output Log, right-click and clear all. Package your project and generate a new Output log. Select all contents, copy and paste into a text doc and post as an attachment here.
The problems in your project causing the build to fail are typically listed as the first lines right after the “Warning/Error Summary.”
