Question: I've been building an Android app on Unity with 3 scenes. The first 2 scenes work perfectly but the last scene was giving me trouble. The game kept crashing on that scene

So while checking out the Unity Forums, they suggested that I copy paste all objects onto a new scene and try and see if it works. 

But now that I've done that, I'm not even able to export it. While building player, my loader gets stuck on this: `Building Scene 2: Name (10/15 Bake Runtime | 1 jobs)`

I've not changed anything else in the settings, and if I remove the 3rd scene, it builds normally. When I only add the 3rd scene it gets stuck on the same.

What could be the problem?

Answer: 
clear your GI cache from the Edit > preferences menu , i had a similar issue and doing so fixed it
if you can't clear the GI cache go to Lightning window and uncheck the auto build checkmark close unity and open again ...
This version of Unity is now outdated and I believe the newer versions of Unity do not have this problem.
