MainActivity в проекте в Android Studio не видит firebase. Выдает ошибку "Unresolved reference 'firebase'."

В MainActivity.kt выдается следующий список ошибок:

• Unresolved reference 'firebase'. line 12-13
• Unresolved reference 'DatabaseReference'. line 21
• Unresolved reference 'FirebaseDatabase'. line 38
• Unresolved reference 'push'. line 73
• Unresolved reference 'addOnSuccessListener'. line 74
• cannot infer type для этого параметра. Specify it explicitly. line 77
• Unresolved reference 'message'. line 79

Все dependencies в build.gradle.kts подключены. Я уже просто не знаю, что может быть причиной. И кэш очищал уже но ничего не помогает
