Apps crashing after updating Lenovo A2010 to Android 5.1 Lollipop

I updated my Lenovo A2010-a to the latest version (Android 5.1): I just clicked on a message that says "You have a new update. Update has downloaded and can be installed" then it opened a new window. On that window, I click on the button "install", then the phone rebooted and was updating (showing a green Android icon). The battery was in normal condition (not low). After that, the phone booted normally. After updating, I have an error on all applications installed on my phone. Error for all applications in one separate window, one after one. With text like this (translated from Russian to English) > Error in application "Google Keyboard" What I can do to resolve that problem?
