Cannot Enable Firebase Authentication in Firebase Console

Question

When trying to enable either the Google sign-in method, or the regular email/password methods, I get an error, something along the lines of "Unknown error encountered". For Google Auth, it says "CREDENTIALS MISSING" in the JSON response, while for Email/Password it says "INVALID_ARGUMENT".

I have tried deleting the project and starting a new one, but the same error persists. I'll include some snippets from the console log below, any help is appreciated!

UPDATE: I can apparently update these settings in Firefox without a problem? I'm not sure what's going on here, but I guess if others have this problem, I would try a different browser?

Is it saying 'Error enabling ...'?
Check if only the native providers are not being enabled and the others such as Google sign in is working or not. For me switching browsers didn't work(Might have worked if I switched to third browser).
If that's the case, check if there is any CORS extension in your browser enabled. It blocks some of the requests. I deleted that and it worked.
