求助两个错误

两个错误，每隔一段时间就弹一次

JsonParseException: The parser encountered an invalid or unexpected character.
Unity.Messenger.Json.Serialization.JsonReader.ReadJsonValue () (at Library/PackageCache/com.unity.messenger@1.0.7-preview/Editor/Scripts/Utils/Json/Serialization/JsonReader.cs:56)

UnityEngine.AsyncOperation.InvokeCompletionEvent () (at D:/unity/Runtime/Export/AsyncOperation.cs:21)
这个错误原因估计是因为我写的OnInspectorGUI导致的，但是问题在于我不把代码挂载到物体上也会出现这个问题。。

Loading assembly failed: "Assets/Scripts/AddComponent/Dll/Microsoft.CSharp.dll"
这个错误是我调用dynamic时提示我缺少东西，我从.NET4.0复制过来的，复制到工程目录下了之后能用dynamic了，可以正常使用，但有时会报这个错误，暂时没看出来影响。


有人知道怎么解决嘛
