r/Unity3D on Reddit: Getting "Assertion failed on expression" when unloading scene

June 13, 2022 -

Here are the errors I'm getting:

Assertion failed on expression: 'offsetIndex != -1'

Assertion failed on expression: 'offsetIndex != -1'
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&

I'm using SceneManager.UnloadSceneAsync then loading a scene right after. This actually works perfectly, but it still throws these errors :( So it's very strange. Actually throws that second error 15 times.

I'm using basically the same script as the SceneLoader in this example project from Unity: https://github.com/UnityTechnologies/open-project-1

Has anybody run into this before? I have no idea what to do. Been very frsutrating.

Check the editor log, there might be something useful there. You should find it in C:\Users\username\AppData\Local\Unity\Editor\Editor.log

Looks like a bug. What were you trying to do?

July 10, 2021 - I cant upgrade sadly because the new player system breaks my code and I'm happy with what I have! I cant see any consequence that I can find but was just wondering if theres something I can do to fix it? ... The messages are harmless, as they only deal with the icons that appear in the Hierarchy window. The assertion mentioned is coming from Unity, so it's hard to say what the issue exactly is - however you can safely delete the offending script, HierarchyIcons.cs, without it interfering with your game.

July 21, 2020 -

So yesterday I saw this error, "Assertion failed on expression: 'res == EAGAIN || !HasAbortingErrors()' I saw it after I changed the size of three prefabs. I ignored it. Then, today when I opened Unity it said it again and when I selected anything in the project menu it randomly selected anything. Someone help.

I'm using unity 2019.3

Note; I posted this on stockflow

Edit I don't know how to use stockflow so I just deleted the post after it was closed

Update:The next day when I open it it says access denied opening file failed. How do I fix this and if I can't. How do I get my files from the project
