Help [FIXED] Dispose of atomic safety handle error when game start

[kaser]

Code:

System.ObjectDisposedException: The UNKNOWN_OBJECT_TYPE has been deallocated, it is not allowed to access it
  at (wrapper managed-to-native) Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle.CheckDeallocateAndThrow_Injected(Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle&)
  at Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle.CheckDeallocateAndThrow (Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle handle) [0x00000] in <b41119cc6741409ea29f63c7f98de938>:0
  at Obi.ObiNativeList`1[T].Dispose (System.Boolean disposing) [0x0003f] in ....\Standard Assets\Vendor\Obi\Scripts\Common\DataStructures\NativeList\ObiNativeList.cs

Hi, I got an error message after game start while using the Obi , as shown above.

Please help me to fix this error

The following is the current version information used in the project

I checked the error code and found strange parts. 
The Dispose process used Bool, but it was not actually used in the Function
Therefore, I added a correction, but I am not sure if this correction is correct. 

After more digging . I think Obi's implementation of Create and Dispose may have missed implementations, resulting in Dispose not running properly.
If anyone is also investigating, welcome to join

#5 Solution

ObiNativeList.cs

Code:

protected void Dispose(bool disposing)
{
    if (isCreated)
    {

        // dispose of compuse buffer representation:
        if (m_ComputeBuffer != null)
        {
            m_ComputeBuffer.Dispose();
        }

        // free unmanaged memory buffer:
        UnsafeUtility.Free(m_AlignedPtr, Allocator.Persistent);
        m_AlignedPtr = null;

#if ENABLE_UNITY_COLLECTIONS_CHECKS
                try
                {
                    // dispose of atomic safety handle:
                    AtomicSafetyHandle.CheckDeallocateAndThrow(m_SafetyHandle);
                    AtomicSafetyHandle.Release(m_SafetyHandle);
                }
                catch (Exception ex)
                {
                    Debug.LogError(ex);
                }
#endif
    }

}

I recently ran into this exception when upgrading my project to Unity 2022.3. In case it matters (for reproducing the exception), in my project the ObiRope objects are within a second scene which is loaded after launch.

Before I found this thread I addressed it by adding the following condition checks within the #if ENABLE_UNITY_COLLECTIONS_CHECKS. Both were necessary.

Code:

if (!AtomicSafetyHandle.IsDefaultValue(m_SafetyHandle) && AtomicSafetyHandle.IsHandleValid(m_SafetyHandle))
{
    // dispose of atomic safety handle:
    AtomicSafetyHandle.CheckDeallocateAndThrow(m_SafetyHandle);
    AtomicSafetyHandle.Release(m_SafetyHandle);
}
