Can't create Firebase project - There was an unknown error while processing the request. Try again

Question

I'm trying to create new project in Firebase but every time I'm getting this error

There was an unknown error while processing the request. Try again.

I have tried to log out and log in but it doesn't work.

How can I solve the problem?

Answer 1

At time of writing, Google Cloud Platform (and by extension, Firebase) is experiencing an incident that prevents new projects from being created. See the links below:

Answer 2

This is because your package name is Already registered in Firebase even if it is deleted, Change the package name and it will start working.
