when used Dictionary

How can I get the value if it non nullable value type this code

            Dictionary<string, object> DictionaryValues = new Dictionary<string, object>();
            RSAParameters publicKey = Storage.Read(_Path + @"\" + "Key.Public");
            DictionaryValues["publicKey"] = publicKey;


            RSAParameters publicKey2 = new RSAParameters();
            if (DictionaryValues.TryGetValue("publicKey", out object obj))
            {
                publicKey2 = obj as RSAParameters;
                
            }

I'm getting an error the as operator must be used with a reference type or nullable type RSAParameters is anon nullable

How can I get the value publicKey from inside the dictionary Please help and thank you everyone
