Uninstall Gpay and install again. Try debug with another device if the issue still persists.

To avoid the app crash - instead of activity.startActivityForResult(intent, GOOGLE_PAY_REQUEST_CODE); do

activity.startActivity(intent);

I tried this and getting the payment done without any app crash but of course if you have a process like writing or giving toast after the success or payment, it wont be possible as the runtime will not listen for the Activity Result as we replaced it with just startActivity in place of startActivityForResult
