Here are a few solutions to try to fix the keyboard issue. Test each one-by-one and see if the keyboard appears:

1. Restart Your Device: Sometimes, simply restarting your device can resolve software glitches or conflicts caused by recent updates. Restarting clears temporary data and resets various system processes, which may help restore the functionality of the keyboard

2. Check for System Updates: Make sure your device’s operating system is up to date. Sometimes, system updates include fixes for compatibility issues with apps.
Reinstall the App: If clearing the cache and data doesn’t resolve the issue, try uninstalling the keyboard app and then reinstalling it from the Google Play Store. This can help ensure that you have the latest version of the app installed without any potential installation errors

3. Clear Keyboard App Cache and Data: Go to Settings > Apps > [Keyboard App] > Storage, then tap on “Clear Cache” and “Clear Data.” This action will reset the app to its default settings and may fix any issues caused by corrupted data.

4. Use a Third-Party Keyboard: As a temporary solution, you can download and use a third-party keyboard app from the Google Play Store until the issue with the default keyboard is resolved
