NavMesh not baking Unity

A billion google reads later and the problem still persists.

I press bake, the bar at the bottom right fills about 5 pixels blue then doesn't do anything. I had recently cleared the old navmesh to bake a new one so it suddenly not working is quite frustrating. The scene is a city-scene with all buildings marked static, the roads marked static, and the ground marked static.

It just says "Exporting tiles" and sits there doing nothing, no matter how long I wait.

 

I know it has been more then a year to this post but can you tell me did you fix the issue. If yes, than how? Because I am having this same problem.
