will export, but with broken scripts

sir please update this guide, it is very outdated.
each time i import an avatar i get this error: Plugin 'Packages/com.vrchat.base/Runtime/VRCSDK/Plugins/VRC.SDK3.Dynamics.Contact.dll' has the same filename as Assembly Definition File 'Assets/Scripts/VRC.SDK3.Dynamics.Contact/VRC.SDK3.Dynamics.Contact.asmdef'. Rename the assemblies to avoid hard to diagnose issues and crashes.
