Phantom wallet no balance.Please help!

Hi!I have such a situation.I bought a new computer, installed phantom, Entered my seed phrase, and I opened a lot of addresses on my wallet, but there is no address on which there was a balance. And I can’t find the key to the secret wallet I don’t know where it is can be located.
Even when I connect phantom to radium where I have ray coins and it does not display them there either. Tell me what to do in such a situation?
