still the same error after restarting

Hi graciely241,

Welcome to the Apple Community.

In the "Related article, linked above ... you might want to scroll down, and continuing following the guidance:

Scroll to "Reinstall iOS or iPadOS"

Says:

If you still see the Restore screen after you restart, you need to reinstall iOS or iPadOS": and gives the steps.

(NB: Seems you need to:

" Connect your device to your computer using the cable that came with your device".)

If you still need help:

There is a "Get Support" link to Apple at top right on this discussion page.

All the best :-)
