Angular 17 App - Hangs on Loading/Splash Screen after sitting idle

I have a new Angular 17 application that is having some strange issue that I can't sort out. After sitting for a period of time (a few hours), when I user tries to visit the site again...it hangs on the loading screen/splash screen. In Chrome, it will eventually show the page unresponsive pop-up.

When I load developer tools, there is no page sources loaded or local storage information. I can't figure out a way to debug it. If the user fully clears cache and reloads, it works fine. Incognito works fine as well. So its something cache related, but not sure how to get at this issue. This is hosted in AWS via an S3 storage bucket.

Again, it only shows up if a user lets things sit for awhile. Clearing the cache fully resolves the issue for a period of time.

Any ideas on how I can debug this? I tried all the chrome extensions and fiddler. Nothing is really getting me to the root issue.

Thank you!
