Unreal 5.6: Ray Trace crashes.

Development Platform & Builds
1

Just upgraded to 5.6. I’m still getting this ray trace bug crash too (im not using ray trace in my project, and disable it entirely both in setting and in my assets.)

[2025.07.16-01.50.47:493][566]LogWindows: Error: appError called: Assertion failed: GFrameCounterRenderThread != PreviousFrameCounter [File:F:\Unreals\UnrealEngine-5.6\Engine\Source\Runtime\Engine\Private\Rendering\RayTracingGeometryManager.cpp] [Line: 582]
FRayTracingGeometryManager::Tick() should only be called once per frame

This is also an old bug from 5.5. I had override everything in engine source codes to stop the crash. Couldn’t believe it’s still here in 5.6. Do they seriously fix any bug that was reported? ><

Just got the same exception! Hasn’t been resolved yet. Do you have any updates?

@KillerPenguin Also running into this issue after upgrading to 5.6. You mentioned having to make code changes to temporarily work around this issue? What did you end up changing?
