Build Error on Post Processing Stack

Greetings,
I 've got 5 Shader errors all with in the same part .cginc
The errors look like this :
Shader error in ‘Hidden/Post FX/Builtin Debug Views’: failed to open source file: ‘Common.cginc’ at line 7 (on d3d11)

Compiling Vertex program with SOURCE_GBUFFER
Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING UNITY_ENABLE_DETAIL_NORMALMAP SHADER_API_DESKTOP UNITY_COLORSPACE_GAMMA UNITY_LIGHT_PROBE_PROXY_VOLUME UNITY_LIGHTMAP_FULL_HDR

Is there a way to solve this ?

I’ve got build error too. Does anyone know how to fix it? (2020.2.1f1 Personal)
