AWS - Amazon.Extensions.S3.Encryption.AmazonS3EncryptionClientBase is attempting to implement an inaccessible interface

Question

While implementing AWS client side encryption created object of AmazonS3EncryptionClientV2 which implements AmazonS3EncryptionClientBase. In local everything working fine but when uploaded on server it is giving following exception

Message: Type 'Amazon.Extensions.S3.Encryption.AmazonS3EncryptionClientBase' from assembly 'Amazon.Extensions.S3.Encryption, Version=1.2.1.0, Culture=neutral, PublicKeyToken=885c28607f98e604' is attempting to implement an inaccessible interface.

Other dll's version as follows,

Amazon.Extensions.S3.Encryption - 1.2.1
AWSSDK.Core -3.5.2
AWSSDK.KeyManagementService -3.5.2.2
AWSSDK.S3 - 3.5.7.8

Also tried with upgrading dll's, still getting same issue

Message: Type 'Amazon.Extensions.S3.Encryption.AmazonS3EncryptionClientBase' from assembly 'Amazon.Extensions.S3.Encryption, Version=2.1.0.0, Culture=neutral, PublicKeyToken=885c28607f98e604' is attempting to implement an inaccessible interface.

Dll versions for above one

Amazon.Extensions.S3.Encryption - 2.1.0
AWSSDK.Core - 3.7.300.3
AWSSDK.KeyManagementService - 3.7.300.3
AWSSDK.S3 - 3.7.300.3

to create client

using (var client = new AmazonS3EncryptionClientV2(PublicKey, SecretKey, config, EncryptionMaterials))
                {
                    client.PutObject(putobject);
                }
