The UATHelper points to these errors:
UATHelper: Packaging (Windows (64-bit)): UnrealBuildTool: UELinkerFixups.cpp.obj : error LNK2019: unresolved external symbol “void __cdecl EmptyLinkFunctionForStaticInitializationCreaturePackRuntimePlugin(void)”
Perhaps you have an undesirable symbol or space in your project’s name? From reading it, it says 'unresolved external symbol “void_cdecl”. Looking through a google search I found this link which might also point you in a helpful direction. Check to make sure all your SDK’s (Windows and Android are all up to date).
Let me know if you have further questions.
Thank you,
