Baking with GPULM sometimes fails while reading totalRaysCastCountBuffer used to measure baking performance.
This happens in RRBakeLightProbesTechnique::Render().

Step to repro:
*Fetch the HDRP graphics repo at sha 196f36cf8498b9099363808ddcf3138d2dab379f
*Download the repro project at https://drive.google.com/file/d/15xPJDyW_0ACY3xnk6niHMxN03LaUvosk/view?usp=sharing
*Update the manifest.json in SponzaHDRP/Packages to point to your local HDRP repo
*Set EnableProbeVolumes = 1, in Runtime/ShaderConfig.cs
*Try baking lighting with it
If bug does not happen on first bake, try clearing baked data and baking again several times.
