Multiple shader errors occur on launching High Definition template

Steps to Repro:
1. Open unity with High Definition template
2. Observe there are multiple shaders errors
3. Go to file > player settings > other settings
4. checkmark allow unsafe code property
5. Window > package manager
6. Update high-end SRP template
7. Observe the shader errors are now resolved
8. Observe the new error

Error:
GI: Setting up material 'Cube_Mat' failed. Does your shader have compilation errors? Object 'Cube' will not be affecting GI.

9. Restart the project observe that a new error now appears and the previous errors are disappeared. The following error occurs every time on restarting the editor, I suspect the shader file is missing. Also, note that sometimes materials won't load the project.

Error:
Shader error in 'HDRenderPipeline/Lit': failed to open source file: 'CoreRP/ShaderLibrary/Common.hlsl' at line 282 (on d3d11)
