UE4 Development Questions,crash

Problem Description:

The UE4 project uses the Terrain Landscape element, and the project is packaged into Quest 2 for testing. After running for a while, it often crashes (we have tested it ourselves, and there is no such problem when the terrain element is excluded. This problem occurs when the terrain is added).

Question added:

After our test: the following optimization settings are enabled for the project. If there is terrain in the scene, it will be packaged to Quest 2 for testing, and it will crash immediately after opening and running (you can see the picture for 1-2 seconds). Turn off the following settings, if there is terrain in the scene, the problem described above will appear.
