Your answer solved this for me. I realise that this is an old question, but can anyone elaborate on why a particle system would need read/write access to the image? – Verwirrt Sep 30 '18 at 13:14
This is the correct answer, solved the problem for me too! – Jawido Kakarot Oct 23 '18 at 18:10

I've got the same error, but with a different reason, so I'd like to share to help others that can get stuck in the same situation:

Cause

I was using a Cone shape for particle emission (Shape tab)
By my own mistake, I selected Texture Default-ParticleSystem
I don't know exactly why, but these Unity Default textures always cause the discussed error
In this case it's tricky to find, because Unity doesn't clearly tell which texture is wrongly set (from the Render tab or from the Shape tab).

Solution

I've just removed the Shape Texture setting it to "None" then the error disappeared

In my Unity it's happening, I don't know the reason or if it happens on other machines, but in my Unity 2019.2.3f1 I'm having to use my own textures instead of the default particle texture. — Tarcisio Júnior, Jan 14 '20 at 09:44
