Unreal Engine 5 Packaged game crashed while playing.

Hi, I’m using Unreal Engine 5.0.3 from source to develop multiplayer game. My packaged game (Standalone) periodically show “not responding” in task manager but the game is still playable. But after playing for about 3-5 minutes later, it crashes without any error shown (Run with Standalone in editor works fine). Any solution please?
