Android: Large vault slow to load on with all plugins disabled

Hi,
Sorry for that unspecific post. As I went through that whole troubleshooting process before (see my posts above), I only wanted to ask, why the startup time of the core plugins are not listed separately => because the sumed up startup time points to a problem of one of the core plugins…?

Another question:
Is there any chance that a suncthing synchronization between android and windows could provoke that slowed down startup process?
