My first lipstick crash after update.

I had about 12 apps open for a while. All native except WhatsApp.

I think I closed one app and all of a sudden the open apps screen froze. App covers do not respond to touch, so I could not switch to apps or use swipe actions. I can scroll up and down, but screen does not clear the open apps covers. App covers shows through on the lock screen and icons.
