It started happening for me as well after upgrade from 2018.2.5. I have absolutely no idea why and definitely this either should be fixed if it is an error in the Engine or the assert removed as it doesn't affect game play whatsoever.

This is the only place on google that the " Assertion failed: Assertion failed on expression: 'verts.size() > 0' " error is mentioned and there is no answer.
This is really annoying, is there at least a way to disable the errors?
So far I have to disable all the navmeshes in my level one by one until I find if it is causing an error. Then if I change it around a little, the error goes away.
I should not be bothered by these errors, they do no affect the game in any way. Please Unity disable these errors from showing up. Forget the cause of them.

I also began seeing this exception when I applied multiple NavMeshes to a scene (one each for multiple agents).
