There are a couple of these crashes. I don't know if this is a dupe of something else that is on file.

The URL for all 4 of these crashes is https://austin-eng.com/webgpu-samples/samples/instancedCube?wgsl=1

3 of these crashes have the index out of bound message.

One of them has the crash message "BindGroupLayout[21] does not exist": bp-3f0ab473-871a-4629-8f66-caf0d0210407
