[allnnde]

Sorry if my English is not good

When running the builder, it ended up giving me the following error

my project has 4 assambly defined Application, Infrastrucubre, Domain, Presentation with its own .asmdef

Looks like a name conflict where your Application namespace is conflicting with UnityEngine.Application.
I raised a PR to add UnityEngine to our build script, which would fix the issue there.
However, it's entirely possible that there will be another name conflict somewhere else.
