The game and the UE engine crash randomly, and the game sometimes stutters for no apparent reason.

After entering the game from the Start menu and then returning to the main menu before re-entering the game, there is a chance that the game and the UE engine will crash together. After repeatedly killing the same boss for an extended period in the game, the game will begin to stutter and drop frames for no apparent reason. Sometimes the home network is normal and the accelerator is also working normally, yet the game still produces stuttering similar to high latency. Regarding the descriptions of the above game instability issues, I can only provide the relevant logs, because the problems are probabilistic events, so it is impossible to reproduce them deliberately. I have already tried reinstalling the game, but the latter two issues still occur with a high probability. Thank you for your understanding.
