Hey there @tbelgrave! Your summoning ritual was successful but you ended up summoning a windows/linux user. Nevertheless let’s see what we can do.
I’ve been seeing some issues with users working in the latest version of Xcode since it had been the new target, and most commonly from projects that were migrated from UE4.27 up. Code signing is a step in verifying all of the project details, dependencies, and targeting and well signing the code. There should be errors listed in the full log that gives us insight into which portion is failing. May we see the full log?
