Bug Editor crashes every often after loading scene and running heavy code.

    I have set up a procedural level generation script that creates a bunch of complex meshes and then converts them into render textures for use as sprites. It also instantiates some other objects. In order to regenerate a level, I reload the scene (asynchronously).
    However, on loading/generating the scene, whether directly after pressing play or after moving onto the next level, it seems Unity has a chance of crashing (about 1/5). None of this seems to be an issue in build (for the small time tested).

    I have tried:
    - Converting function to coroutine and adding short delay between each heavy processing
    - Looking at crash logs but they are unhelpful - they just say Crash!! after running the generate function
    - Checking for recursion (although this usually freezes up rather than directly crashes) - there are no while loops in code, and I'm pretty sure the for loops are purely iterative.

    I am unaware if it corresponds to the seed given.

    Any ideas on what could be causing these infuriating crashes?

    Here is the crashlog, please let me know if you would like to see any code snippets (the whole level gen script is really long).
    Code (CSharp):

    The part following „Crash!!!“ would be most interesting. There is nothing following that? That would be unusual.

    You should add logging or use the debugger to check at which state in generating the editor tends to crash.

    Would also help if you shared some of the code. How heavy is heavy? Perhaps it‘s simply too much.

    Actually nevermind the issue appears to have fixed itself. Apologies for the inconvenience.
