Mesh won't select in blender 2.93

Hi,

I’m new to blender but I think I know how to do basic selections so I have no clue why a mesh on my 3D character model won’t select. I am trying to bind my rigify rig to my model mesh. I’m suppose to select the mesh first then select the rigify rig. The mesh is suppose to highlight in an orange colour while the rig should be yellow. The problem is the mesh won’t highlight at all. No clue why. Any help please?

thanks in advance.

Can you link and image or .blend file of the problem?

Make sure the object is selectable in the outliner. White highlight means selectable.
Outliner

Thanks for the reply. I just reinstalled blender because I had other issues as well and after the reinstall it was fine.
