To uninstall the latest update, head to your phone’s settings menu. (You can usually find a gear icon by swiping down on the notification shade at the top of the screen. Click the gear or find the settings in your app launcher.)
Scroll down and find “apps” or “applications.” Click that and then, select “all apps” and find Android System Webview.
Click the app and on the next screen, you should see a three-dot menu at the top right. Click that menu and select “uninstall updates.”
You can also find Android System Webview by heading to the “installed apps” section of the Google Play Store and clicking uninstall. This will remove the latest update and your applications should be restored immediately.
This isn’t the best solution for the problem but it’s the only viable option to get your other apps up and running.
