    Also has same issue. It crashes both in game and in editor. It worked fine in 2019.1.8 and then checked in 2019.2, 2019.1.10, 2019.1.12, 2019.1.14 - it fails.

    I can assume this is what is crashing my project as well, as I narrowed it down to a prefab with a particle effect that would crash the scene on opening it. I also saw this happen since 2019.1.9.
