My chromebook kept on popping up “(insert app) has stopped/keeps stopping” so I took the advice to update the apps using Google Play Store. Now I can’t get out of the play store. The pop up won’t let me open anything else, shift+esc doesn’t work, and I can’t click on anything except ‘close app’ which only brings back the pop up a few seconds later. Please help! I can’t do anything on my laptop.
