Compute Shader property not set error when entering play mode with path tracing and PBR sky

Steps to reproduce:

1. Open Outdoors scene in attached project.
2. Enable RTVolume in the hierarchy.
3. Enter Play Mode.

Actual results: 
Following error is logged when entering play mode.

Compute shader (SkyLUTGenerator): Property (_ShadowmapCascadeAtlas) at kernel index (3) is not set
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Expected results: 

No error.

Reproducible with versions: 

6000.0.36f1, 6000.1.0b4, 6000.2.0a4

Not reproducible with versions: 2022.3.60f1

Tested on (OS): 

Windows

Notes:

• Does not reproduce on 2022.3.60f1,  only on 6,x streams
• The error only displays once, and doesn't seem to affect rendering, so maybe it is just some race condition when setting up a buffer/texture.
• The error occurs when trying to enter play mode with pathtracing and the PBR sky active. or if you switch to game view while PathTracer's convergence is ongoing.
• Does not repro when convergence is finished
