Game crashes on minecraft logo launch screen continually after it updates it's resource packs or whenever you exit a world and it says loading resources with wifi on. However if you only open the app with wifi disabled the app will not crash on a fresh reinstall and will continue not to crash until you turn wifi on and the stated above conditions occur to make the app crash continually. So it seems to be an issue with updating/accessing certain resource packs on the latest version.
App worked fine on 1.5.0, and for clarification no custom resource packs are installed and the issue persists through a fresh reinstall unless you use the workaround posted and use the app solely with no wifi.
Edit: The app seems to just crash again now even with the wifi workaround, as others have posted.
Edit 2: See Ishmaeel comment, temporary workaround is working for me while we wait for the issue to be fixed.
