IL2CPP error with Entities Package

[Tested on version 2021.1.1f1 , 2020.2.1f1, 2020.1.3f1]

Hi. I found a bug when i build with IL2CPP scripting backend.
Normally i build a project and run on Android, it’s find.
But when i add [com.unity.Entities] package and build with IL2CPP, the application is stopping after Logo splashing at the very first time.
Please try to make an empty project and add [com.unity.Entities] package, build on Android device with IL2CPP and run the app.

It’s solved…
Entities package is not available from version 2020.
We should use version 2019.x when we use DOTS system on the project.
