I had the same issue after a Windows update on my Inspiron 15 7000 gaming laptop and I was able to resolve the issue by disabling the Intel (R) HD Graphics 630 display adapter while keeping my NVIDIA GeForce GTX 1050 adapter enabled. 
thanks nerdtron! I disabled the Intel graphics and it fixed it for me too ;)
Glad it helped, it was an annoying bug that wasted a lot of precious development time to solve.
We used to got a similar error in latest 2020.1.0f1 and finally solved it. I post the investigation here and hopefully it can help someone.
Investigation steps:
The Error popup is
check Editor.log
Launched and connected shader compiler UnityShaderCompiler.exe after 0.05 seconds Shader compiler: failed to get available platforms. Likely the shader compiler crashed at initialization time. Will retry. Error: Failed writing data to socket
check shadercomplier-UnityShaderComplier.exe0.log
check editor folder and find the D3Dcompiler_47.dll has been lost
copy and paste the dll to target location and the problem has been solved
It's happening to me the same error. In all the versions i have installed (2020.1.f1, 2020.1.b9, 2019.1) and i tried absolutely everything and it's still not working. How can i solve this?
The Editor.log can be found at "C:\Users\username\AppData\Local\Unity\Editor"
The D3Dcompiler_47.dll is supposed to be located at "C:\Program Files\Unity\Hub\Editor\2020.1.0f1c1\Editor\Data\Tools"
where do i find shadercompiler-UnityShaderCompiler.exe0.log ?
where do i find shadercompiler-UnityShaderCompiler.exe0.log ?
One student in my class had the same issue. What I noticed is she had Norton 360 anti virus installed, I disabled it before copying D3Dcompiler_47.dll over from a different PC, this solved the issue. $$anonymous$$y theory is the anti virus killed the DLL file.
Even I'm facing the same problem while moving fast or while using terrain or while using particle system especially when I'm using the particle system. Editor I'm using is 2020.1.6f1. And the laptop im using dell inspiron 14 3000 i3 processor (idk if its the laptop that is causing the problem or the editor). Please help and thank you in advance
The same as me 我刚好5小时前也遇到了这个问题 你简直像是我的分身来问出这个问题的
BTW, this fatal error happened to me when i tried to copy my project from my laptop to my desktop;I had tried all the ways to settle the tdr problem, it did fit the tdr problem that may happen in some other procedures, but it does not solve the problem in unity3d. It seems that disabling gpu acceleration does not work, modifying the regedit does not work either. The problem also happen in 2020.1.0.a11 version, which I happened to install these two alpha version altogether; In my laptop with 2020.1.0.a11 version, it works all fine.
This is likely not the case for everyone, but i have an nvidia gpu, and turning off image sharpening completely fixed this error for me, if there's an option for that in your gpu driver, try that?
So here are my experiences with this issue:
Every time I upgrade my project it will open it successfully, but after rebooting the PC the problem returns.
After uninstalling Unity and Hub and reinstalling everything, the problem is unchanged and persists.
After uninstalling Unity and Hub, updating my drivers and reinstalling, opens project successfully, but after rebooting PC it returns once more.
I'm studying Games Design in college and this is messing with my grades as I'm not able to work on my project. I have not found a single fix or solution for this issue anywhere.
EDIT: I finally solved this issue! The latest unity hub update caused this issue! Turns out VPN's and Unity Hub do not go together at all! Turning my VPN off and opening my project worked for me, so I've gone into my VPN and specifically selected unity as an exception to bypass the VPN, allowing me to be protected and run unity. I'd also like to add for those of you that do not use a VPN and are receiving this error, it is most likely due to your firewall messing with the UnityShaderCompiler.exe. I really hope this helped everyone as I know it's frustrating!
The error message does nothing to indicate a connectivity issue, but my VPN was the problem for me as well.
