Error: Assertion failed on expression: ShouldRunBehaviour()

Unity Engine

Hi! So suddenly I started to see this error in the editor, it doesnt seems to affect gameplay but it appeared out of nowhere.

This is the StackTrace that appears in the log:

However I cant figure what is happening, I think it might be that PlayerLoop is executing twice somehow? If anyone knows anything please let me know, thanks!

UPDATE: It seems to be coming from a Gameobject called “DelayedActionManager”, appearing in DontDestroyOnLoad scene, it didnt use to appear before. It seems to be related to the use of Addressables :open_mouth:
Anyone?

I’m getting the same failing assertion and the editor logs tell this:
Assertion failed on expression: ‘ShouldRunBehaviour()’
(Filename: ./Runtime/Mono/MonoBehaviour.cpp Line: 856)

And yes, it came out of nowhere, and i think is highly related to addressables cause im struggling these days to make them working correctly.

I just had this same issue immediately after upgrading the Addressables package from 1.16.16 to 1.18.4. I had hundreds of the same Assertion failed error. I was able to fix it in my case by downgrading to 1.17.17.

I haven’t debugged it further or reported a bug because i have a deadline i’m working towards and 1.17.17 includes the synchronous API i needed. I might be able to come back to it and report it next week or later, but if someone else gets to it first that’d be great.
