Resolution Note:
There are 2 canvases in the scene - UI and 1 for the cursor. They both have a sort order of 0. In the player they just happen to get sorted in a different order, its a common problem when sorting identical values, different platforms may do it differently or a change in initialization may happen to cause them to be added in a different order. I did not look into why this time it happens as the root problem is the same, they both have the same sort order.
So when the cursor canvas happens to be first the mouse raycaster selects the actual cursor and not the button behind it.
Do the following:
Disable raycast target on the mouse cursor so it cant select itself.
Change the UI canvas sort order to 1 so that its the same in the player and editor.
