Unity standard assets has error

Hey running the latest Unity version and I installed the unity standard asset pack from the store and I get the following error
"Assets/Editor/CrossPlatformInput/CrossPlatformInputInitialize.cs(91,34): error CS0619: UnityEditor.BuildTargetGroup.WebPlayer' is obsolete: WebPlayer was removed in 5.4, consider using WebGL’

Why does a Unity Standard asset pack have errors?

Is this no longer a supported asset pack?

If this is no longer supported then why not say which version it is for in the store
Is this package not for this version?

Many questions, What is the deal with this?

Nothing really hard to fix judging by the script

Just remove BuildTargetGroup.WebPlayer and leave the other build targets

For example:

         private static BuildTargetGroup[] buildTargetGroups = new BuildTargetGroup[]
         {
             BuildTargetGroup.Standalone,
             BuildTargetGroup.WebPlayer,
             BuildTargetGroup.Android,
             BuildTargetGroup.iOS,
             BuildTargetGroup.WP8,
             BuildTargetGroup.BlackBerry
         };

Becomes

         private static BuildTargetGroup[] buildTargetGroups = new BuildTargetGroup[]
         {
             BuildTargetGroup.Standalone,
             BuildTargetGroup.Android,
             BuildTargetGroup.iOS,
             BuildTargetGroup.WP8,
             BuildTargetGroup.BlackBerry
         };

Sooo, why does this package have errors at all?

To resolve this issue, add the following line;

BuildTargetGroup.WebGL,

Like so…

private static BuildTargetGroup[] buildTargetGroups = new BuildTargetGroup[]
            {
                BuildTargetGroup.Standalone,
                BuildTargetGroup.WebGL,
                BuildTargetGroup.Android,
                BuildTargetGroup.iOS,
                BuildTargetGroup.WP8,
                BuildTargetGroup.BlackBerry
            };

NB Tested on Unity 2020.3.31f1
