After importing the datasmith runtime, the program crashes when exiting the runtime.

When I import a simple model into the scene, there is no problem.
But if I try to import an entire scene at runtime, exit the runtime, or reset the datasmith runtime actor, the program will crash. And when I packaged the program, I also encountered an error message as follows:

Assertion failed: Pair != nullptr [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Map.h] [Line: 656]

The operation after import is ok, but it cannot exit normally. Even if I destroy all the additional actors of the datasmith runtime actor, reset the datasmith runtime actor will still result in an error.

I am using UE5.1.1 version.
Computer configuration:
amd 3900x
rtx4090
ddr4 3600 32G

Hello, I am getting same issue. Did you solve it?
Is there any workaround?

Not resolved.I have tried different methods,At present, I can only confirm that this issue will not be encountered when the datasmith folder has a capacity of less than 100M.

I have the same problem as yours, I want to try to split the datasmith file into 3 or 4 files.
Maybe in this way the problem would be solved.
But I don’t know how to split datasmith file without destroying the model data.
