Unfortunately the callstack comes right from renderer. I do not believe the crash to come from simply having a low framerate, rather it is exasperating some other issue.

Assertion failed: IntFitsIn(In) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Templates\UnrealTemplate.h] [Line: 174] Loss of data caused by narrowing conversion, In = -4611686018427387904
