Out of curiosity does anyone with this issue have reduced motion turned on? I was having this same problem with that enabled. After disabling it I have not had a springboard freeze in 3 days. Not sure if that was the fix or if it's coincidence.
I’ve had it happen almost daily since going to iOS 11 and 11.0.1. I use reduce motion on. I’ve only notice it happen when trying to open an app that is located in a folder.
