Bangle js 2 - after selecting yes or no from E.showPrompt, the screen stays blank.

Ahh - yes, E.showPrompt has to remove your layout's input handlers so they don't get called when you tap on the screen.

To re-add them, I think it should be fine to just do layout.setUI();layout.render(); although I think if you're using 'lazy' rendering you might need a layout.forgetLazyState() before layout.render();

Just FYI you only need to call Bangle.loadWidgets(); once at the start of your app - once they're loaded they don't need re-loading.
