    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.
