Export android with compute shader doesn't work on unity 2018

Hi everyone!
I make a little application to use Compute Shader on Android.
In unity, 2017 and more, it’s work fine.
Export unity for android works perfectly on 2017.3.0p3, but it doesn’t work on 2018.2.10f1.
Every parameters are same.
For my global project, I can’t use 2017.3, so i ask you your help on this…
Thank you

a little precision :
When i say it doesn’t work on 2018.2.10f1, it means that all application work but compute shader give a black image.
Thank you for your help
