Hi Samantha,
Thank you for posting your question here!
This typically happens when Spotlight is disabled by policy or its background services are corrupted. On some work or HP enterprise builds Spotlight is intentionally turned off by management policies. On personal devices it can usually be fixed by re enabling Spotlight in the registry and resetting the Content Delivery Manager cache followed by a restart.
Step 1 If this is a work device Spotlight can be disabled by policy. Open Settings > Go to Personalization
If Lock screen page is missing Spotlight entirely that points to policy
Step 2 services reset. Open Settings > Go to Apps > Installed apps > Find Windows Spotlight or System components if listed Repair then Reset
Step 3 Press Windows key + R > Type regedit > Go to HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion > ContentDeliveryManager > Set these to 1 > RotatingLockScreenEnabled > RotatingLockScreenOverlayEnabled > Exit and restart
If this is an HP or enterprise build IT may have Spotlight disabled intentionally.
