    I am getting this error randomly after updating to the latest version of unity ( 2022.2.21f1 ) NullReferenceException: SerializedObject of SerializedProperty has been Disposed. I am unable to figure out what is causing this issue, error log wont take me to the code that is the issue. If I restart unity it goes away. If i enter playmode and then exit the error will start again. I get thousands of these errors.

    EDIT: I found that this issue happens when selecting any object in the editor. If I deselect all objects so I have nothing selected I do not get this error

    EDIT: Restarting unity, deleting library folder, resetting ui. Fixes the issue for a few minutes then the error returns.

    EDIT: Upgraded to 2022.3.0f1 and am running into the issue less but seems to occur when messing with array lists in the inspector, also still happening when selection any object in the scene view

    Code (CSharp):

    We're having this bug too since upgrading to 2022.3.6f1. We're also thinking it's related to arrays

    J’ai le même problème avec deux tableaux justement qui ne s’affichent plus dans l’inspecteur..

    Having the same issue. Started this week after a complex logic implementation using a array of struct and a few <int,int> dictionarys (declared inside the scope of the method) in a MonoBehaviour class.

    This public array of struct already existed before and was consumed by simpler methods in this and other classes, so I believe it is not related to its existence in the serialization of this class fields.

    I'm using Unity 2022.3.7f1

    EDIT:
    Useful information: happens mostly when attached to Visual Studio for debug.
    After exiting play mode the exception continues to throw until closing the Editor.
