Summary
have been trying to render a simple background pan for a shot, but Unreal crashes during or when I run the simulate button ( not always on the simulate button) I hope someone can point me to whats going on in here, my City Sample is in version 5.7, newly downloaded all I did was made a panning camera to render it.
here is the crash log:

Steps to Reproduce
download the city sample
open small city
load a portion shoot
create a sequencer
set to 24 fps
create a shot track
set to 24 fps
add a camera cut track
create a camera dolly animation
add to move render queue
then render local.
also it help to go in and out of simulate just to make sure the traffic and crowds are initalized.
I usually add more to the render settings but since I’m trying to find was causes this
I chose to put less in it. sometimes it will renderder a few frames before it crash
sometime I get the crash even by pressing the simulate button( not even rendering yet)
Expected Result
render completes
Observed Result
crash during render of sometime when entering game mode
Platform(s)
windows 11

Additional Notes
seems like a raytracing error, the curbs on the street seems to be black when running in path tracing, but I digress I have to make a default render first before revisiting that one, as I intended to render the shots in path trace if I can manage it, to be clear I rendered with deferred rendering, not path trace.
