我有一个带有应用内购买功能的应用程序。我使用最后一个计费库：

    implementation 'com.android.billingclient:billing:4.0.0'
    implementation 'com.android.billingclient:billing-ktx:4.0.0'

我的问题是：每次 Nexus 5X 设备上的某个用户尝试购买时，都会抛出异常：

Caused by java.lang.NullPointerException
Attempt to invoke virtual method 'android.content.IntentSender android.app.PendingIntent.getIntentSender()' on a null object reference

com.android.billingclient.api.ProxyBillingActivity.onCreate (ProxyBillingActivity.java:8)

仅在此设备上抛出异常。为什么会发生这种情况？怎么解决呢？
