System Information
Operating system: Ubuntu 22.04
Graphics card: Nvidia GTX 1050

Blender Version
Broken: 3.2.0 stable
Worked: 3.1.2 stable

Short description of error
When you have multiple Vertex Colors attributes/layers for a mesh, the PLY exporter used to export the selected/highlighted one as Vertex Colors.
In 3.2.0 the exporter just exports the first Vertex Colors in alphabetic order regardless which one you choose.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
vc12.blend
Try export the mesh "Grid" with different Vertex Colors layers.

D14718: Fix blender/blender#89017: PLY files from various programs are incompatible due to their exporters, and vertex-colored point clouds do not import color. should resolve this report.

I'm able to replicate.

D14718 should resolve this report.

We should probably also mention this task there in patch If D14718 also fixes this
