So with that point the first symbol I have is "{" and after the first slash I have "G", after the second slash "C".... I believe its an encrypted key because I don't recognize any private key like I saw on differents tutorial or guides ... ?
i have never used bitcoin.com wallet but according to this link: https://www.bitcoin.com/guides/how-to-import-and-export-bitcoin-private-keys they don't allow you to export your keys unencrypted. which means what you have is an AES encrypted result which contains your IV, encryption type, iterations, and encrypted keys in base64 so it would look like this:
you can't import that into electrum because it doesn't have any decryption option in its GUI for these cases.
so your only (easy) option is to find your 12 word recovery phrase (seed) and use that to recover your private keys. read this topic for more information: https://bitcointalksearch.org/topic/how-to-export-decrypted-private-key-from-bitcoin-wallet-app-wil-give-you-tip-2644000
