After I’d Updated Unity to 2020.1, all the shaders have become rendering Purple. When I delete /Libraries- nothing happines. When I reimport URP plugin- unity drops me errors:
Library\PackageCache\com.unity.render-pipelines.core@7.3.1\Runtime\Volume\VolumeManager.cs(55,23): error CS0246: The type or namespace name ‘Collider’ could not be found (are you missing a using directive or an assembly reference?)
Library\PackageCache\com.unity.render-pipelines.core@7.3.1\Runtime\Volume\Volume.cs(142,14): error CS0246: The type or namespace name 'Collider' could not be found (are you missing a using directive or an assembly reference?)
