Question

So I just wanted to import my 2d character into unity and when I drag the PSB file into unity. It just gives me this error:

NullReferenceException: Max Size: SerializedProperty is null

I found the solution!!! you can close the platform settings of the PSD import error that is causing the problem

Create a C# script called FixPSDImporter and paste this inside and fixed!

 public static class FixPSDImporter
    {
        [UnityEditor.InitializeOnLoadMethod]
        public static void ResetPSDImporterFoldout()
        {
            UnityEditor.EditorPrefs.DeleteKey("PSDImporterEditor.m_PlatformSettingsFoldout");
        }
    }
