When asking a question, it’s best to provide as much information as possible:

  1. Share your entire relevant scripts in a code block rather than a screenshot:

```csharp
// your copy/pasted code here
```
  1. Include any errors or warnings you encountered, along with their exact messages.
  2. Explain what you were trying to achieve.
  3. Describe what actually happened versus what you expected. (Doesn’t work, is not a good description)
  4. List any troubleshooting steps you’ve already attempted.
  5. Provide steps to reproduce the problem, if possible.

This makes your question clearer and shows that you respect others’ time:

  • Using a code block lets people easily copy and test your script instead of retyping it.
  • Sharing the full script allows them to run it on their own machines.
  • Providing the exact error message (if any) helps identify the issue more efficiently.
  • Clearly stating your goal prevents guesswork about what you’re trying to accomplish.
  • Describing what actually happened (rather than just what you expected) helps them reproduce the issue.
  • Sharing what you’ve already tried prevents them from wasting time on the same solutions.
  • Overall, clear and complete information saves everyone from playing “20 questions” just to understand your problem.

This specific error, coming from this location (eg, NOT your code, such as ApiUpdater (as seen here), UnityEditor.Graphs or UIElements or PlasticSCM), is often fixed by either Reset Layouts (upper right) or else Right-click Project, Reimport-All.

If that doesn’t fix it, try upgrading all relevant packages, or installing those packages in a blank project and seeing if you can bring stuff up. You can also try a different version of Unity, but remember that upgrading is a one-way process, so make a full backup or use source control correctly.

If that doesn’t fix it, file a bug with Unity.

OTHERWISE… if it was your error (it does not look like it is!!!), then…

The answer is always the same… ALWAYS!

How to fix a NullReferenceException error

Three steps to success:

  • Identify what is null ← any other action taken before this step is WASTED TIME
  • Identify why it is null
  • Fix that

NullReference is the single most common error while programming. Fixing it is always the same.
