What went wrong
It crashes with
thread 'main' panicked at 'Buffer slices can not be empty', C:\Users\elabajaba\.cargo\registry\src\index.crates.io-6f17d22bba15001f\wgpu-0.16.2\src\lib.rs:2362:39

Additional information
I tested it on both vulkan and dx12.
It used to work on bevy main. #8910 is when it started crashing.
