Short description of error
On complex scenes when I set the Viewport Shading to Vertex Color Blender crashes. Its usually on complex scenes
I noticed it's crashing when have my Instance Collection on the scene and it works when I hide it. But I'm not sure it only happens in this case.

Sending the file. To reproduce the error just open it and try to put the Vertex Color option. The file is the Default with the objects added.

Found out why! It's related to hair.

To replicate: Add a Suzane, change the Viewport Shading to Vertex Colors, Add particles > Hair. Change the mode to Vertex Paint and it crashes.

This happens on the default file and in all projects that have hair particles.
