Shader error in unity 2019.3.1f1

Just not working. Showing purple image (means a mistake in shader) :'(

I had the same issue, you just need to set the shaders yourself. Check out #12

Did anybody got it working? I tried the procedure , but the materials were pink and then when i set the shaders myself, it didn't get the desired effect. Am I missing something?

I also had the same issue, something about Graphics Blit, I assumed it was a Unity 2020 thing. So I just made my own shader that follows similar logic using RenderTexture https://github.com/zephyo/UI-Blur-LWRP-2020.
