    We've had to turn off shadows while we wait for the fix to be released.

    This issue also occurred in our project.
    We have confirmed that it has also occurred in Unity 2019.4.1f1 released today.
    The call stack when the phenomenon occurred was as follows.

    If needed I can provide crash dumps. Btw for me it's not related to Terrain at all but rather happens when drawing the Game View (in game) after switching to another scene

    Unity.exe caused an Access Violation (0xc0000005)

    Also happens for me in 2019.4.0f1. Moving certain lines of C# Code around fixes the problem, but it's very odd - maybe it indicates some form of memory corruption
