Can't select objects in scene view when they have a layer

If i give an object a special layer, in my case the layer “ground”, i cant select them i scene view anymore. I have this problems in multiple unity versions and i restarted unity multiple times. Can someone please help me

If anyone stumbles upon this issue in future click the “Layers” button at the top right corner just beside the Layout button and from the list make sure you have your desired layer visible and selectable.
