The HLSL support for shaders is based on ReSharper C++ and requires ReSharper C++ to be installed. This is always the case for Rider, but it is possible to install ReSharper without C++ support.
Current workaround is to install ReSharper with C++ support.
Licensing is no longer a problem as ReSharper C++ is included in both the ReSharper and dotUltimate licensing packs. Once installed, it's possible to disable C++, but this will also disable HLSL support in ShaderLab files.

This is still happening with latest version, 1 year+ later since this issue was reported. Is there a fix planned for this?
The problem is that the Unity plugin requires ReSharper C++ for language support for shaders (HLSL is treated as a dialect of C/C++). If ReSharper is installed without C++ support, then these errors are shown - the current workaround is to install ReSharper C++.
The first step to a fix is to split up the current Unity plugin DLL. This currently contains all Unity related code - C# analysis and quick fixes, but also shader language support. By moving to a separate assembly, we should be able to prevent loading an assembly that depends on features that aren't available or installed. However, this will mean that shader support is unavailable, and there will be no language support for ShaderLab or HLSL files.
This work is also required for various other technical reasons, and is about to start, targeting the 2022.1 release.
