[URGENT] Payfort UI causes app crash when canceling card purchase transaction

[mohanedy]

When I initiate a card purchase transaction, the Payfort UI is displayed. However, if I try to go back and cancel the transaction, the app crashes with a java.lang.RuntimeException and a java.lang.NullPointerException.

Steps to reproduce

1. Start a card purchase transaction
2. Tap the back button to cancel the transaction
3. Observe the app crash

Expected behavior

The app should not crash and the transaction should be canceled.

Actual behavior

The app crashes and shows the following error log:

@jawaid-Ahmed try to change the compile SDK to v33 till they fix this issue in the native Android plugin. This worked for me.
