My Safari is not working. Can’t search or delete history.

Hello MyiPhonexissues,

This page can provide assistance for an app not opening as expected (note that the reinstall step may not apply to Safari): If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support

1. Close and reopen the app

Force the app to close. Then open the app to see if it works as expected.

2. Restart your device

Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.

3. Check for updates

To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.

4. Delete the app, then redownload it

Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.

Be sure to also check for any restrictions on the device by seeing if Screen Time is enabled at Settings > Screen Time.

If Screen Time is off, and the above steps hadn't helped, you may also check for a profile or Mobile Device Management (MDM) on the device. The path to this may vary but on the latest version it will be Settings > General > VPN & Device Management.

Cheers.
