I have had the One UI Home app crash quite often when switching apps using the recent apps button (double tap).
A force close and a cache clearing seems to temporarily fix it. However, it comes back after a while.
Ugh... Getting quite annoying. I didn't realize I used it so much until it stopped working correctly. It is freezing almost as often as it is working.
Removal of Home Up got it to look right. However, the swipe up feature returns an empty seven with only a "Close All" button. In "One Handed Mode", as I have it set, the gesture for recents returns the full list.
