Common Solutions
Restart your phone: A simple restart can resolve temporary software glitches causing the keyboard to disappear.
Clear the keyboard app's cache and data: This removes corrupted or temporary files that may be causing the issue. Go to Settings > Apps (or Applications), find your keyboard app (like Gboard), and select Clear data and Clear cache.
Update your keyboard app and Android OS: Outdated software can lead to bugs and conflicts. Check for updates in the Google Play Store for your keyboard app and in your device's settings for system updates.
Switch to a different keyboard: Temporarily enable another keyboard in your Settings > System > Keyboard > On-screen keyboard to see if the issue is specific to your current keyboard.
