"Google keeps stopping" after Android Oreo update
There is some critical error for the new android Oreo (for me is nexus 6p) which make a system crash on the desktop (google now launcher) and on settings (you can't open app list). It is can be created by any of your applications which you need to find. So only way to remove the app, in this case, it is to use a google play application or maybe some other launchers. For me, it was "6 Minute English". I find it via installing nova launcher and on the common app list, the application was shown without a logo,  with green robot image instead.
