Small correction in my previous reply: In step 4, the spacebar may have to be pressed 2-4 times rather than just once for it to be reproduced. Regardless, it still occurs while interacting with the GameObject with a component that starts/stops a coroutine.

Just a note: The second error (Coroutine couldn't be started because the the game object '<name>' is inactive.) won't actually be reproduced by the above steps but instead by the following:
1. Open the attached “BugRepro” project
2. Open the “Assets/Scenes/Level3.unity“ Scene
3. Enter the Play Mode
4. Press Spacebar
5. Immediately open the “Assets/Scenes/MainMenu.unity“ Scene while in Play Mode
6. Observe the Console window

Resolution Note:
This behaviour is expected as were guarding against these scenarios where scene hierarchy changes are being made when there is a scene change happening. Hence the error message asking to avoid these scenarios.
In order to solve it try checking object to be dechilded is active (It would be better to check for parent object but this is close enough as the whole scene is being unloaded anyway)
