We are working on a huge project.
100k -ish files

Every single time Play is pressed on unity editor it hangs for around 2 minuites.

I tried to isolate the issue.

steps i tried.
1.) I moved from version 122 to version 150.
2.) unchecking everything that i can uncheck in the settings.

I also tried to disable every dll. in the folder. aside from the
Google.VersionHandlerImpl

it still loads for an unacceptable amount of time.

This however does not happen when i try it in a empty project.

I also are unable to profile on what in the DLL's are triggering this massive spike in loading time. as the calls in a DLL does not show up in a profiler.

I can now fix the issue by importing the ExternalDependencyManager once in a while when building, and disable them after...

UNITY VERSION 2019.3.X
