Solving UE-QZSim Crash Issue in Quarantine Zone Final Checkpoint Demo

I’m having a major problem with the Quarantine Zone demo and need some help.

Every time I try to run the last checkpoint in the demo, my game crashes completely. The error message says something like “UE-QZSim Game Has Crashed And Will Close” and then everything shuts down.

This happens consistently when I reach the final area of the demo. I’ve tried restarting my computer and verifying the game files, but nothing seems to work. The crash always occurs at the same spot.

Has anyone else encountered this specific crash in the Quarantine Zone demo? I’m really frustrated because I can’t complete the demo to see if I want to buy the full game. Any suggestions for fixing this would be greatly appreciated.

My system should be able to handle the game since other parts of the demo run fine. It’s just this one section that keeps causing problems.

That final checkpoint is definitely buggy. I had to disable my antivirus temporarily to get through it since some security software can interfere with UE games. Also try running the game as administrator if you haven’t already. The demo’s optimization is pretty rough compared to the full release.

I faced the same issue in the demo. Lowering my graphics settings helped me get past that checkpoint, so give that a shot if you haven’t already.

I remember having this exact crash and it turned out to be a memory issue. The final checkpoint is really demanding and even though the rest of the demo runs fine, that last part pushes systems harder. Try closing any background programs before loading that checkpoint. Also check if your RAM usage is high when it crashes.

Check if your GPU drivers are up to date. That specific error usually happens when there’s a driver conflict with Unreal Engine games.

Try deleting your save file for that checkpoint and replay from the previous one. Worked for me when I had similar crashes.
