    ICANFLY342's steps are slightly off, in my testing. You shouldn't need to turn on "Cast Shadows", and the two systems only need to be visible in the Game window. If they are not in view of the camera, you can go look at them in scene view and not get the error.

    I can reproduce this error with the following steps:

    Create New Project
    1. Add a Particle System to the scene on any object.
    2. Add a LineRenderer to the scene on any object.
    Note: They can be on their own separate objects, or on the same object, it doesn't matter.
    3. Both Particle System and LineRenderer must be in the view of the Camera.
    4. Error appears almost immediately after hitting play, and repeats over and over.

    This bug can be reproduced in every 2018.4 version starting from 2018.4.18f1.
    And it can be reproduced in every 2019.3 version starting from 2019.3.0b12.

    For those looking to avoid this error:
    Unity 2018.4.17f1 is the last 2018.4 version where this doesn't happen.
    And Unity 2019.3.0b11 is the last 2019.3 version where this doesn't happen.

    I'm having the issue after updating to 2019.3.9f1, so it looks like it's still happening.

    I just updated to 2018.4.20f1 and am getting this error, seems to be caused by Particle Systems.

    I can reproduce this bug in all the 2019.3.x versions that I have:

    Create New Project
    - Add a Particle System, goto Renderer-Tab and turn on "Cast Shadows"
    - Add a LineRenderer to the scene
    - Both Particle System and LineRenderer must be visible in either Game or Scene window!
    - Press Play, wait a few seconds... the error should show up
