Short description of error
When trying to parent this mesh to the armature with Automatic Weights, Blender crashes.
Interestingly though, if you simply enter and leave edit mode beforehand, it doesn't crash!
I think the mesh was created with the Quadriflow remesher, maybe that's relevant?

Exact steps for others to reproduce the error

Download blend: phil.crashycrash.blend
Ctrl+P -> Automatic Weights
Crash.

I can confirm the crash:

Strange that the mesh looks valid at first.
This may be related to the recent reports on corrupted mesh because in #80468 it was mentioned about connecting the armature to the mesh.
So I am confirming as a bug.

Bisecting shows that the crash seems to be caused by d7282537f0.
@PabloDobarro could you take a look at this?

I can't reproduce it. I also find weird that that commit is the cause because that does not include any functionality that can be used from the UI to create a color datalayer in order to make it crash, it is just the datalayer definition.

@PabloDobarro Have you tried with an ASAN-enabled build?

I can't reproduce this any more with current master, so I'll assume that it's been fixed in the mean time.
