Connecting AirPods in Control Centre blocks my iPhone and iPad

When I connect my AirPods in the Control Centre, the view of the control centre stays on my screen. Through that, I can see my homescreen but I cannot do anything. Whatever I try, the view of the control centre stays on my screen. This is happening on my iPad mini3 and the iPhoneX is bought yesterday. My iPad mini2 and my former iPhone (8) haven no problems with it.

When I connect the AirPods via the Settings>Bluetooth>AirPods everything works fine.

But I want the shortcut through the control centre working as well. Especcialy for phonically, this is very handy.

I already disconnected the AirPods, reset them to factory settings, but the problem still remains.

If anyone has a solutions, I would appreciate it.
