Always crashed when running in standalone game mode

UE v5.2.1
Cesium for Unreal v2.0.0
Also crashed in the Cesium for Unreal Samples.

When I play the level with “Selected Viewport” or “New Editor Window” mode, it run successfully.
It still runs successfully after packaging
The problem only appears in standalone game mode,

I tried to modifying the code:
// Only fixup flags in the editor, when not in play mode
if (!IsValid(GEditor) || GEditor->IsPlaySessionInProgress())
return false;

It doesn’t work

This problem happened on another computer either.

How to solve this problem?
