There is a good chance to solve it out if you can find the wallet's wallet.aes.json in your pc. It's an encrypted json file that has your private key.
The encryption password is the same password that you use to login to blockchain.com. If you can find that file you can open a new wallet with the very same key and gain cotrol over your funds.
Just be careful and don't share that password with anybody.
Assuming that blockchain.com provides me with my wallet.aes.json (supposedly they keep the wallets backed up on their servers) and I have my wallet ID and password, but not my seed phrase. What software would I use to open/decrypt the wallet? Wouldn't it still ask for email authorization? (Which I am not receiving)
