Recovering an Argent wallet will recover your Argent account as a whole, so if you are using both Vault and zkSync wallets, you will get them both back after recovery.
If you have an active Argent Vault
The wallet recovery process is the same as for Argent Vault, you can find the available options here.
If you don't have Argent Vault
If you have your encrypted key, you can proceed with the off-chain recovery.
If you never saved your encrypted key, you can recover wallet with guardians. This process will activate your Argent vault and you will need to pay network fee for the recovery + activation transaction. The recovery with guardians is a process involving Layer 1 transaction, and will likely be costly since it relies on Ethereum gas prices.
After recovery with guardians your zkSync owner key will change and you will need to claim your wallet again.
