UE5 Screen Freeze but audio plays, no logs - how to troubleshoot?

Hello,

I have an issue where I have a horde-style map where players fight enemies that respawn.

Randomly the game will freeze and the audio will continue to play. Since it is a screen freeze and not a crash I don’t have a log. Is there any way to pinpoint the problem?

What I have tried,

-Duplicate the map
-Increase the Loop Iterations count
-Updated my drivers

What I know:
It seems to be local to a certain map, so the problem is for sure with that map.
The blueprint code is nothing fancy, it basically ticks enemy spawns and has a timer, very basic survival map.

I am normally pretty good at fixing issues, but the problem is that I dont have anything to go off because it is a frame freeze and not a crash with an error. Any ideas on where to start would be helpful!

This is for the horde mode on the game Fossilfuel 2 to be specific.

I think I might have fixed this. I believe there was a loop where I was spawning actors, and that the actors were either spawning on top of one another or there was just a runaway loop in general.

I went around and added a bunch of “delay until next tick” blockers, and I also cranked up the loop iterations count to a massive amount.

It seems to have worked… for now.
