I’m working on different types of scriptable objects for various stuff in my project and whenever I go into play mode with one of these scriptable objects selected Unity gives me multiple ArgumentNullException errors. I select another object from the scene, hit play and everything is fine. Is there a way to prevent these errors or is it something about the serialization in Unity and nothing can be done?
Could be anything. Does the exception originate from your code, or entirely Unity GUI? In the latter case try updating to the latest patch level.
It’s not my code, and like I said I can go into play mode normally if I deselect these scriptable objects. I’m using Unity LTS 2022.3.
This is how the errors look like:
ArgumentNullException: Value cannot be null.

What particular 2022.3 version?
Probably updated in the more recent versions. Do you happen to using Odin Inspector at all, too?
I’m not using Odin but you were right, it went away after I upgraded the editor from 2022.3.10f1 to 2022.3.40f1.
