    Resolution Note (fix version 2022.2):

    Adding an event in the event handler will no longer cause a crash. It is important to note that the case was a user error. The event that the user would add in the event handler would be executed instantly, creating another event over and over, ending with a stack overflow, crashing the unity editor. Could a play queued be used here instead? https://docs.unity3d.com/ScriptReference/Animation.PlayQueued.html
