I get error in hdrp after upgrading 2020 version to 2021

After the update I get these errors

Library\PackageCache\com.unity.render-pipelines.high-definition@12.1.7\Runtime\Lighting\LightLoop\LightLoop.cs(114,68): error CS0117: ‘ShaderConfig’ does not contain a definition for ‘FPTLMaxLightCount’

How can I fix these errors?

Check the package manager whether any packages need updating.
