I bought a brand new iphone 12 max pro 512 Gb unblocked From the Apple store and when I turned the phone on it’s showing the hello in different languages then when I swipe it’s asking me to put a passcode on a brand new that don’t have one yet

Take it back to the Apple Store and get it resolved. There is a procedure to reset the device's passcode however that will just put you through the troubleshooting phase on a brand new iPhone. Take it back is my recommendation to you.

if it started out with the hello in different languages.. this is supposed to be an indication that the device is free and clear..

Are you sure that it's not asking you to enter your Apple ID password?

If it's saying passcode are you sure it's not asking you to set a new passcode?

Mine has the same problem, but it does not even ask for a password

Good Points. Perhaps the iPhone is asking to set up a new Passcode.
