I resolved the Issue by using Visual Studio to attach the Debugger to the Cooking process called “UnrealEditor-Cmd.exe” while it was running.
I looked through the Stack frames for any functions that had arguments with asset path strings. I went up to the function arguments and it said “W_SkillTreeWide” was the asset throwing the exception. I looked further up the Stack trace for anything useful and there was function with an asset reference to the Asset loading “W_SkillTreeWide” and it was my PlayerController.
I went into Unreal and removed any references to “W_SkillTreeWide” in my PlayerController and cooked the project. BUILD SUCCESSFUL!!!
Screenshots of process below.
