первый раз, когда я использую billingclient, но у меня проблема, консоль выдает мне ошибку: RecyclerView BillingClient: адаптер не подключен; пропуск макета, и иногда он загружает RecyclerView, а иногда нет, то есть я ввожу действие, и иногда оно загружает его, и много раз оно не загружается.

Я оставляю код эксперту, который будет направлять меня, и я могу помочь себе понять, где у меня есть ошибка
