Upon opening my project, I have ALOT of Errors?

I am not sure why this is coming up. Last time I had an error like this, it said it was related to my Package Manager and Asset Store. Once I took them off the dock it was fixed. I’m unsure what these are related to. This is what comes up in the console:

NullReferenceException: Object reference not set to an instance of an object UnityEditor.UIElements.UIElementsEditorUtility…cctor () (at <6d0b5326886a4f0e8ed4ea356b37330b>:0) Rethrow as TypeInitializationException: The type initializer for ‘UnityEditor.UIElements.UIElementsEditorUtility’ threw an exception.

Never mind I fixed it! For anyone else with these errors, check any assets you import and see if there are any Demo/ Example Scenes. Delete them but ensure you don’t accidentally delete any assets. This should clear up any errors. In mine, I believe some of these scene files were from an older version of Unity and contained older script files as well.
