FIrebase Errors\Problems

Hi to all. Well let me describe the problem.
When i make the build in log i can see these Firebase error(and it breaks firebase and google cloud saves)


So, what i tried till now.
- Deleting Firebase and intalling it both thourhg package manager and unity packages(version 6.16.1)
-Reinstalling Google External Dependency Resolver and launching its Resolve stuff(it said that all was resolved)
- checking for different duplicate classes and stuff
- Exported project to Android Studio and making build there.
Once in between of all these actions ive got a crash in one of the builds

But in the end, i anyway receive errors like that -
