My iOS 14 home screen widget intermittently flickers in the widget gallery view. This happens sometimes when I run the widget from the simulator and sometimes happens in production. It seems like the widget is failing to instantiate before any of my code is run. I'm not able to hit any breakpoints. Has anyone seen this before?

I'm updating my widget from StaticConfiguration to IntentConfiguration. When I do so, existing widgets installed within simulators and on my iPhone device either show a blank screen or a placeholder screen and fail to initialize. Is there a safe way to upgrade my widget configuration? I would hate to break the widget for our existing users and force them to manually reinstall.
