NullReferenceException but

Shikaki34167 · December 5, 2023, 4:43pm

I got these errors whilst using Unity 2023.2.1f1:

The game is working fine, it is text based but includes various buttons. But, as I clicked on play, the errors started to gather rapidly and in a short amount of time, I wa sleft with:

the NullReferenceException errors were automatic and spammed a lot in the console.

Although I didn’t get it again, I want to know what is the cause of those errors as I can read it says sth related to binding.

We are working on a fix.

adrian-miasik · December 17, 2023, 10:59pm

Heya, I’m running into something similar on a similar editor version.

I’m glad to hear you’re working on a fix, but I couldn’t find any tickets related to this on the bug tracker: https://issuetracker.unity3d.com/

https://unity3d.com/search?refinement=issues&gq=UnityEngine.Bindings.ThrowHelper.ThrowNullReferenceException

Can you please provide a ticket number or additional context for this? Would love to know if it’s relevant to my case and if I can track its resolution.

Here’s the case. It might some time before it’s available.

adrian-miasik · December 21, 2023, 10:12pm

Thanks for providing the case, much appreciated.
I’ll be following and testing once it gets resolved. Will try report back if there’s any hiccups.

nightdriveinteractive · January 19, 2024, 6:01am

The issue tracker case for this bug says it’s fixed in 2023.2.5f1, however, the bug still seems to happen for me after updating to 2023.2.5.

griendeau_unity · January 22, 2024, 7:56pm

@nightdriveinteractive Can you share the callstack of the exception you’re seeing please?

nightdriveinteractive · January 24, 2024, 11:46am

Here’s my callstack. I thought it was the same as above at first glance, but it does differ.

Hope it helps!

griendeau_unity · January 24, 2024, 2:46pm

Yes, that’s not a problem with UI Toolkit, looks more like a rendering/lighting problem in the scene. You can try the Graphics forums for that one : https://forum.unity.com/categories/graphics.75/

I want to thank you. I had this problem until now and it was very hard for me to work on my project.

Also if anyone wants to know how i fixed it:
I just deleted the global volume

jabaro · February 25, 2025, 11:25pm

I’m having what I think is a similar problem in 6000.0.32. It happens every so often when I Run. Quitting Unity and restarting fixes the problem, usually. Sometimes I have to restart twice. Sometimes it happens after just 2-3 runs, sometimes not for quite a while. Not a serious problem, mostly just annoying because of the wasted time. It is pretty annoying to have to restart Unity so frequently.

That’s what it’s been doing today, every 1 or 2 runs I have to restart Unity. This is getting pretty annoying.

spiney199 · March 12, 2025, 12:39am

Have you updated your editor version since then? 6000.0.32 is about 3 months out of date by now. Potentially this has been fixed since then, but work checking the release notes.
