timberkt | Easy Android logging with Kotlin and Timber

I have added implementation 'com.jakewharton.timber:timber:4.7.1' to my Kotlin project and now I get the following Gradle errors:

here are the steps to reproduce the issue:

1. click on google signin Button.
2. choose "use another account"
3. sign in with the new account and this should bring you back to the app.
4. app only shows dark overlay and consent form or callback(to onActivityResult) is not working.

then if i touch the screen the dark overlay goes away, at this time if i press the google button again it automatically logs me in with the account. I tried a few apps like stackoverflow,traveloka, airBNB, my own simple app with a google SSO button and glassdoor,lazada, etc and a few others and all of them give an error after getting to option 3.

I thought perhaps it was the [oauth consent form]:

i filled it out but im only requesting email as a google SSO options. so i filled out the form but nothing after waiting a while.

if you want to see my full code, its pretty standard google SSO button and its here: the class is called LoginFragment.kt

but let me post the class here that handles the login:
