After Migration from Older MacBook Pro to New MacBook Pro M5 "Colors in Model" list is Not Populated

The only SketchUp problem I thought I had after migration of over 900,000 files to a new MacBook Pro 2026 M5 Pro was VRay unable to find my license. That problem was fixed today with the help of a VRay Tech Support person remotely opeating my computer doing some magic stuff. Now I find another weird problem. The “Colors in Model” list is blank. Does anyone have any idea of how this list in populated and what could make it not work? It’s a very useful feature that I don’t want to have to workaround.

This is an issue with some Macs. There have been other threads on the topic but I’m not sure there’s a solution yet.
