2021.3.19f1 Collider Gizmos fail to appear in scene view

Collider gizmos do not appear in my scene view. I have attempted:

  • Project Settings > Physics 2D > Gizmos > Always Show Colliders
  • Toggled the gizmo visibility in the editor view
  • ensured that the gizmos specific to colliders were enabled in the gizmo menu
  • checked to make sure that the mesh I have selected has a collider on it
  • ensured that the collider in question was not collapsed in the inspector
  • checked the scaling of the parent and child objects (including testing with a plain cube gameobject with a sphere collider)
  • restarted unity (it works just fine in other projects)

What additional settings can I toggle to make the gizmo visible? For a brief moment, I saw the proper sphere collider wireframe, but then it was gone again upon deleting and re-adding the collider.

:EDIT:
I am able to get the collider wireframe to appear using the following steps:

  • select the obj with the collider on it
  • play the game and watch the object fall in scene view
  • stop the game
  • now, the collider wireframe is visible. However, when I deselect the object and reselect it, the collider wireframe disappears again, only ever becoming visible (for a single time) after enabling “play” mode and stopping.
