Hi. I found that NavMeshComponents simply not work in Unity 2019.3b7. It crashes in IL2CPP iOS Player build at NavMeshManager.LoadData(). Also I found that it is already reported long time ago (alpha stage) and still not fixed. https://issuetracker.unity3d.com/issues/crash-in-navmeshmanager-on-mobile-with-il2cpp The official repository said: You can see, they not mentioned 2019.x. But the repository has actually 2019.3 branch so I checked it of course. Then simply found that 2019.3 branch has no changes for its main code from last master commit (about 1 year ago) except project update. I want to know whether 2019.3 will be support NavMeshComponents, and is it safe to use NavMeshComponents itself for 2019.x cycles because it seems that simply abandoned. Thanks. PS. I used NavMeshComponents in Unity 2019.2 without any issue, so I posted to 2019.3 beta forum.
