@PradyumnaKrishna, I make the changes.

So to solve this issue I generate a random symmetric key and encrypt the message with the symmetric key and then encrypt the symmetric key with the recipient public key.

For the receiver end, I am sending the symmetric key along with iv and the encrypted message, the receiver has to first decrypt the symmetric key using their private key and then decrypt the message using the decrypted symmetric key.
