Short description of error
I was watching the Blender video called: "Workspaces - Blender 2.80 Fundamentals" and follow all the steps from minute 1:11 to the minute 1:40 (approximately thirty seconds) and I made a render (the render was OK) and when I closed the render window, my object disappeared. To see again my object I had to press TAB to return to the "Edit Mode" and again TAB to return to "Sculpt Mode".
Thanks.

Exact steps for others to reproduce the error

You can follow the instructions in the video made by Blender called: "Workspaces - Blender 2.80 Fundamentals" and follow all the steps from minute 1:11 to the minute 1:40 (approximately thirty seconds) and after that you have to make a render and when already finished it, you have to close the render window. After that, there is no object on the screen or if you move it, it disappears.
