CustomRenderTexture.Update() causes silent crash after dropping a Prefab into a Scene

Camera

-

Steps to reproduce:
1. Open User-supplied project ("ProjectorSimulator_SRP.zip")
2. Open "Sample" Scene
3. Drag 'VideoProjector' Asset located in Assets -> ProjectorSimulator into Hierarchy

Reproduced in: 2017.4.25f1, 2018.13.f1, 2019.1.0f2, 2019.2.0a11

Note: After the first crash occurs, when you open the project again, it will crash after 2 seconds.
The third time Unity will freeze upon opening.

The crash no longer happens after removing 'Light' Component from the VideoProjector -> Red/Grey, so I'm sending it to Lighting Grabbag

The Light component also has "HD Additional Light Data" and "Additional Shadow Data" Components attached, which are only removed along with the 'Light' Component.
Combined, they take more than a thousand lines, so I did not do much testing inside those scripts, if, however, such testing is needed, ping me on Slack.

    Resolution Note (fix version 2020.1):

    We fixed the issue where outstanding updates for a CustomRenderTexture would trigger a crash of the Editor when that CustomRenderTexture got destroyed.

    I overcame this issue by ensuring the textures of the Graphics.CopyTexture function in CookieCreator.cs were a certain format. Crash was definitely caused by CopyTexture.
