    Don't have a solid reproduction yet. But recently faced a constant crash issue in the Editor, where everytime I hit play, the editor crashed.

    The same stacktrace in every crash report:

    The code that it seems to think caused the error:

    crash_2.png

    So I decided to put a Debug.Log before the instantiate. And suddenly, no more crash!

    Which makes me think, is Unity not reloading asembly definitions or compiling the dll's correctly on Editor startup?
    Doesn't happen in all cases, seemingly random. But when it does happen, it causes constant crashes until the asmdef is reloaded again.

    Hi @CDF,

    We'd need a reproduction project to properly investigate this. Based on your description of the problem we couldn't find any known issues that would fit 100%. Nonetheless, It might be worth checking out if the issue still occurs in a19 since a couple of fixes that could be related landed there.

    Just wanted to mention that I currently seem to experience the same bug - whenever I start and play my project for the first time since starting my computer, it crashes right at the beginning. According to the log in an Instantiate() too. After restarting Unity, it works.

    This with Unity 2020.3.22f1, but happened with earlier versions too.

    I also have this problem which is happening multiple times a day when I press Play or when a script compiles, I don't see anything related to Instantiate, just this
