But there is still a chance to save the coins.
You need to find the private key from the eth address through the converter https://iancoleman.io/bip39/ and import it into the cronos wallet.
It is advisable to withdraw all other coins to another wallet before entering the seed into the converter, and at the end create a new seed on the ledger for security.
Of course, for a beginner, this will all be difficult, but I defend that there is a chance to save coins.
There's a lot that can go wrong here if a user doesn't fully understand what he's doing with such tools and in which security environment it's done.
