Code to reproduce

Since, it is related to payments, and there are many blocks which tied to our backend, it is hard to provide sample app. Snippets as follows:

class PurchaseDialogFragment : DialogFragment() {

  @Inject
  lateinit var stripe: Stripe

  /**
   * Booking created with state as PENDING
   **/
  fun onBookingCreated(clientSecret: String) {
    confirmPayment(
      ConfirmPaymentIntentParams.create(
        clientSecret,
        PurchaseDialogFragment.PAYMENT_INTENT_RETURN_URL
      )
    )
  }

  private fun confirmPayment(params: ConfirmPaymentIntentParams) {
    stripe.confirmPayment(this, params.buildUiCustomization())
  }

/**
   * Build UI customization for payment auth flow for Stripe (extension utility)
   */
  fun ConfirmPaymentIntentParams.buildUiCustomization(): ConfirmPaymentIntentParams {
    // Optional: customize the payment authentication experience
    val uiCustomization = PaymentAuthConfig.Stripe3ds2UiCustomization.Builder().build()
    PaymentAuthConfig.init(
      PaymentAuthConfig.Builder()
        .set3ds2Config(
          PaymentAuthConfig.Stripe3ds2Config.Builder()
            // set a 5 minute timeout for challenge flow
            .setTimeout(5)
            // customize the UI of the challenge flow
            .setUiCustomization(uiCustomization)
            .build()
        )
        .build()
    )
    return this
  }

  override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    // Stripe listener
    stripe.onPaymentResult(requestCode, data,
      object : ApiResultCallback<PaymentIntentResult> {
        override fun onSuccess(result: PaymentIntentResult) {
          // handle success
        }

        override fun onError(e: Exception) {
          // handle error
        }
      })
  }
}

@msimar thanks for filing. I was able to reproduce this crash. It looks like it only happens with Fragments, not Activities. I'll post a fix shortly.
