Is the Google App important? What does it do?

The app updated 3 days ago and since then it keeps crashing and messing up my tablet. It turned off my keyboard and made getting past the lock screen quite an endeavor. 2 hours with Samsung tech support and no solution, except disabling the screen lock so at least I won’t get locked out again. They gave me a Geek Squad ticket to go have it factory reset as we couldn’t do it without a keyboard. Seems drastic, so I took it on myself to clear the app cache and force stop it. That got my keyboard back, but I’m still getting crash notices. Is this an app I can safely disable? Safely uninstall and reinstall? The fact that it took out my keyboard makes me afraid it’s needed to operate the tablet.

I’ve seen other people having this problem when I searched, so hopefully google’s going to fix it soon (although my Puxel experience does not give me confidence). But in the meantime I’m wondering if there’s anything I can do. If you reply, please use plain English, I am not conversant in technospeak. Thanks for any help.
