If the payment UI is shown, you cannot use the debugger in the dev tools, as the UI is acting like a modal dialog.
Only way to help yourself out is to press ESC, which closes the UI and continue debugging, if you're already on a breakpoint or debugger statement. The problem here is, that even if you can continue debugging, the paymentRequest itself will be canceled.
