Did you add or copy paste something connected to your android manifest? The error you’re encountering might be related to incorrectly formatted apostrophes or quotation marks. Try typing it manually.
Maybe on this part
Change it to this (type the apostrophes and don’t copy paste)
com.google.android.gms.games.APP_ID=“@string/app_id”
com.google.android.gms.appstate.APP_ID=“@string/app_id”
android:exported=“true”
