Problem:
Hitting G for game view or trying to play in editor would result in a crash with the following error:

Assertion failed: ClearValue.ColorBinding == EClearBinding::EColorBound [File:D:/build/++UE5/Sync/Engine/Source/Runtime/D3D12RHI/Private/D3D12Commands.cpp] [Line: 1363] Texture: MotionBlur.SceneColor does not have a color bound for fast clears

Hardware:

Ryzen 7 3800X

Workaround:
Disable Motion Blur in Project Settings or in your Post Process Volume, this will stop the crashes.

If anyone knows how I can set MotionBlur.SceneColor that would be awesome, it doesn’t come up in the console when I search it. Or it looks like maybe it’s a texture?

The postprocessing volume has a scene color setting that appears to default to null. Setting the color there doesn’t seem to resolve the issue.

I have the same issue. If you have a Oculus Rift 1, unplug it from the PC and the crash do not occur anymore. Has this been reported to Epic?

Happens to me with the Oculus Rift (2nd version).

How to fix without removing my Rift?

Further searching solved this. If you untick/disable the motion blur parameter in the project settings it fixes itself.

Thank you! This solved it right up! I really didn’t wan to remove my OVR headset, so this is how you do it without having to disconnect your headset: Disable motion blur. Thanks again, Loucsam!
