Publishing a model to Roblox breaks the viewport

Bug Reports Studio Bugs

Publishing a model stops the viewport from rendering, requiring studio to be restarted to fix it.

Reproduction:

  1. Open an empty baseplate
  2. In the Explorer, right click on anything (e.g. the SpawnLocation), press Save to Roblox, and upload it as a model
  3. Close the publish window after it’s done. The viewport will no longer update when you try to move the camera. Opening and closing a script will leave the script editor on the screen.
