Dealing with The Same Gmail OTP Issue | Dubbed Version

It is very important to understand that this is working as intended, ie. is not a mistake.

It happens when users do not have any or enough recovery options that they can use, and Google want to try to help in the ONLY other way that they can.

If you are facing this issue then hopefully you have access to the Gmail's inbox somewhere else. Or maybe you are forwarding from that Gmail to another email of yours?
