Just the other day, Google rolled out an update for "Android System Webview". This is a component that is needed to display Internet content inside applications.
The program update caused crashes in applications that depend on the Internet. VPN clients, some browsers, online games, instant messengers, and Google apps were broken.
On March 23, the Google Workspace website reported that the problem was fixed with the next update. You need to update "Android System Webview View" and "Google Chrome" via "Google Play".
How to Fix the Recent App Crashes
To use WatfordHert's method, go to the main Android Settings menu, then tap "Apps & Notifications" (just "Applications" on some phones). Find Android System WebView in the list and tap it. (If you can't see the app, check the three-dot menu and tap "show system apps.") Do not disable the app.
Tap the three-dot menu at the top right of this screen, then select "Uninstall updates." This won't uninstall Android System WebView completely—it's an essential component, and many apps will cease to function without it. Instead, it will remove the updates installed from the Play Store and restore it to the version that came with your phone. This isn't ideal, but it's better than having a phone that can't go thirty seconds without an app crash.
Tap "OK" on the warning that pops up, and you should be done. If you're still seeing constant app crashes, try a reboot of your phone.
We can't personally test this method on all the phones being affected, but multiple Reddit users are reporting that it's working for them. If you see the app crashing problem return, try repeating the steps above—the Play Store may have automatically updated the app without alerting you. According commenters like Jorell, this method may not work on devices running older versions of Android—try uninstalling the updates from the Chrome browser itself instead.
Update Android System WebView
If you want a more permanent solution, Google quickly issued an update to the Android System WebView application in the early hours of March 23rd. It should be rolling out on the Play Store right now, but if you don't want to wait, it's available on APK Mirror as a direct download. The version number you're looking for is 89.0.4389.105.
According to a service update posted to the Google Workspace Status Dashboard, this version of the app should fix the problems with other reliant apps crashing. Note that users who are already on the developer previews for Android 12 shouldn't need this—they're already running early versions of Chrome 90, and WebView gets updated along with its.
