My first Apple ID is apparently not active

I was playing Mellon playground one day when I got a notification from settings telling me to enter the password for my Apple ID. So I enter it and I get a notification saying “this Apple account is not active” I’m trying to move my stuff to a new Apple account which is the one I’m currently using, but it keeps telling me to enter the password to turn off find my iPad. So that means I can’t reset it without iTunes, I can’t sign out, or install any apps unless I install them on a different device because it tells me “can’t ask for permission: your iTunes and iCloud account are different”. I tried resetting the password but it says “couldn’t verify identity: your Apple account is not active” I have managed to sign in to messages with a different Apple ID. If anyone knows how to fix this, please help me.
