Just to add to my previous comment:
After Setting MeshCompression to 'Off' on all the models that go into the AssetBundles, everything works fine again.

Seems to happen in Unity 2018.3.0f2 again, when meshes are loaded from Assetbundles. Some have MeshCompression=low, some have it off.
Trying to get a small repro project ready.

We just ran into this same issue in 2018.3.0b8. After exhausting a bunch of other theories, I tried checking for this "fixed" bug and it resolved the issue. The game (or editor) would crash whenever we loaded a mesh from an asset bundle that had medium mesh compression enabled. We were also getting loads of assertion failures in the logs (Assertion failed on expression: 'meshVD.GetDataPtr() == NULL'). Disabling mesh compression, while not ideal, got rid of the assertions and the crash.

We have also run into this issue. In the editor we crash with a [Position out of bounds!] error. But when we run the code on an iOS device we still get the same error message/stack trace but we don't crash. Instead, meshes simply don't render on the device. We did some digging around and the meshes are empty (no verts). Crossing our fingers for a timely fix as we are trying to move our project to 2017.3.
