Hi ease22,
Thanks for using Apple Support Communities. We understand that your keyboard is appearing when searching the App Library. We're happy to look into this with you.
If you haven't already done so, start with a restart of your iPhone. A restart is a simple step that can resolve a variety of issues You can see how here: Restart your iPhone
Next, if you have any third-party keyboards, try removing those and testing if this behavior continues after. See how here: About the keyboards settings on your iPhone, iPad, and iPod touch
You may also want to upgrade your iOS as iOS 14.3 was recently released. For steps on updating check out:
Update your iPhone, iPad, or iPod touch
Thanks.
