Tilemap "The Handle has already been released" ?

Unity Engine
,
1

I am not sure why and when exactly, but I get the following errors sometimes, especially when stop playing inside Unity editor

The Handle has already been released.
UnityEngine.StackTraceUtility:ExtractStackTrace ()
Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle:Release (Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle)
UnityEngine.Tilemaps.ITilemap:Finalize ()

Using Unity 2021.2

From the look of the error message, it’s got to do with tilemaps?

Thanks! I would love to know the nature of the issue, did it contributed to any kinds of memory leak issue?

It should not have contributed to any memory leaks. The issue with this is that the clean up for Tilemap Handles is done more than once, instead of just once. Each subsequent clean up call will result in the error message you have seen.
