There is a menu on my ipad screen preventing me from opening or unlocking my ipad?

By design, you can always perform a forced-restart of your iPad without interacting with the iPad screen:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

You’re very welcome. 😊

The arrows don't correspond to the model ipad that I have. I have no start button, taskbar or menu bar.
