Can't open any projects: Shader compiler initialization error :Failed to read D3Dcompiler_47.DLL?

Wed, 12 Oct 2022 09:52:35 +0000

Hello, yesterday I downloaded a project from a repository that needed a 2020.3.7f1 version, upon opening the project, the following error raised:
Shader compiler initialization error: Failed to read D30 Compile DLL file something is preventing access to D3DCompiler 47. dl. Check your Editor installation integrity, file access rights and antivirus configuration.

I created a new project and the same happened when opening it. Versions 2019.3.16f1 and 2021.17.f1 also have the same issue.
I have tried reinstalling the version and updating the Unity hub. I have DirectX installed, I also checked the System32 folder and the dll is there, plus it has reading permissions.
Common causes - incomplete download so suggested to re-install. So I did it 3-4 times
Due to Anti Virus - permission issue so as per suggestions open the project in a public folder.

Is there any known fix that isn't downgrading the version? Any help or possible fix would be appreciated.
