How Restart Failed Setup - iPhone 14 Pro Max

Assuming you do know your correct Passcode, your phone should say how long it is unavailable and you wait that exact amount of time to enter the correct passcode. If, however, you don't know the correct passcode, you will need to use a computer to fully erase your phone and set it up again, from the last backup you hopefully have.

See these two links:

If you see an iPhone, iPad, or Apple Vision Pro unavailable message or Security Lockout screen - Apple Support

Or if you don't know the actual passcode, see this --> If you forgot your iPhone passcode or your iPhone is disabled - Apple Support
