    Found temporary fix:
    Need to modify LiveLinkPlayerSystemGroup.cs and SceneSystem.cs

    LiveLinkPlayerSystemGroup.cs
    In "LiveLinkPlayerSystemGroup.cs" (Library\PackageCache\com.unity.entities@0.8.0-preview.8\Unity.Scenes.Hybrid\LiveLink\LiveLinkPlayerSystemGroup.cs)

    Move var bootstrapFilePath = GetBootStrapPath(); above #if UNITY_ANDROID
    Before:
    Code (CSharp):
    1.         protected override void OnCreate()
    2.         {
    3. #if UNITY_ANDROID
    4.             var uwrFile = new UnityWebRequest(SceneSystem.GetBootStrapPath());
    5.             uwrFile.SendWebRequest();
    6.             while(!uwrFile.isDone) {}
    7.  
    8.             if (uwrFile.isNetworkError || uwrFile.isHttpError)
    9.             {
    10.                 Enabled = false;
    11.             }
    12.             else
    13.             {
    14.                 Enabled = true;
    15.             }
    16. #else
    17.             var bootstrapFilePath = GetBootStrapPath(); //<----- This (Line 45)
    18.             Enabled = File.Exists(bootstrapFilePath);
    19. #endif
    After:
    Code (CSharp):
    1.         protected override void OnCreate()
    2.         {
    3.             var bootstrapFilePath = GetBootStrapPath(); //<----- To here (Line 31)
    4. #if UNITY_ANDROID
    5.             var uwrFile = new UnityWebRequest(SceneSystem.GetBootStrapPath());
    6.             uwrFile.SendWebRequest();
    7.             while(!uwrFile.isDone) {}
    8.  
    9.             if (uwrFile.isNetworkError || uwrFile.isHttpError)
    10.             {
    11.                 Enabled = false;
    12.             }
    13.             else
    14.             {
    15.                 Enabled = true;
    16.             }
    17. #else
    18.             Enabled = File.Exists(bootstrapFilePath);
    19. #endif

    SceneSystem.cs
    In "SceneSystem.cs" (Library\PackageCache\com.unity.entities@0.8.0-preview.8\Unity.Scenes.Hybrid\SceneSystem.cs)

    Add static internal string GetBootStrapPath() method and add k_BootstrapFileName string variable
    Before:
    Code (CSharp):
    1.     public class SceneSystem : ComponentSystem
    2.     {
    3.         public const string k_SceneInfoFileName = "catalog.bin";
    4.  
    5.         static internal string GetSceneInfoPath()
    6.         {
    7.             return Path.Combine(Application.streamingAssetsPath, k_SceneInfoFileName);
    8.         }
    After:
    Code (CSharp):
    1.     public class SceneSystem : ComponentSystem
    2.     {
    3.         public const string k_BootstrapFileName = "livelink-bootstrap.txt"; //<------ This line
    4.         public const string k_SceneInfoFileName = "catalog.bin";
    5.         //This function below
    6.         static internal string GetBootStrapPath()
    7.         {
    8.             return Path.Combine(Application.streamingAssetsPath, k_BootstrapFileName);
    9.         }
    10.         //-----------------------------
    11.         static internal string GetSceneInfoPath()
    12.         {
    13.             return Path.Combine(Application.streamingAssetsPath, k_SceneInfoFileName);
    14.         }

    66.   }
    67. }
    68.  

    Tested using my current project, I'm not using LiveLink, so not sure if that's working, but it builds and runs successfully.

    Edit: Just found out that packages revert themselves when you close then reopen the editor, so you have to modify these every time you reopen the editor

    Open the SceneSystem.cs and LiveLinkPlayerSystemGroup.cs files (by searching in the Project tab for "SceneSystem" and "LiveLinkPlayerSystemGroup" with In Packages selected), then do the solution I provided my previous post:

    You have to change both files every time you reopen your project, until this is updated.

    Or just move it to Packages folder from PackagesCache and it will made package local and would't change it automatically.

    Which one are you suggesting to move from PackagesCache to the Packages folder?

    If you're not interested about LiveLink functionality ( I'm not using it too ), you could only remove "SceneSystem.", just after #if UNITY_ANDROID.

    The file then would looks like so:
    Code (CSharp):
    1. protected override void OnCreate()
    2.         {
    3.          var bootstrapFilePath = GetBootStrapPath(); // <--as said, this is moved from below.
    4. #if UNITY_ANDROID
    5.             var uwrFile = new UnityWebRequest(GetBootStrapPath()); // <-- here the "SceneSystem." is removed.
    6.             uwrFile.SendWebRequest();
    7.             while(!uwrFile.isDone) {}
    8.  
    9.             if (uwrFile.isNetworkError || uwrFile.isHttpError)
    10.             {
    11.                 Enabled = false;
    12.             }
    13.             else
    14.             {
    15.                 Enabled = true;
    16.             }
    17. #else
    18.          Enabled = File.Exists(bootstrapFilePath);
    19. #endif
    20.             if (Enabled)
    21.             {
    22.                 if (!UnityEngine.Networking.PlayerConnection.PlayerConnection.instance.isConnected)
    23.                     Debug.LogError("Failed to connect to the Editor.\nAn Editor connection is required for LiveLink to work.");
    24.              
    25.                 using (var rdr = File.OpenText(bootstrapFilePath))
    26.                 {
    27.                     var buildConfigurationGUID = new Hash128(rdr.ReadLine());
    28.                     LiveLinkSessionId = long.Parse(rdr.ReadLine() ?? throw new Exception("Expected line in bootstrap containing session id!"));
    29.                     World.GetOrCreateSystem<SceneSystem>().BuildConfigurationGUID = buildConfigurationGUID;
    30.                 }
    31.             }
    32.         }
    33.
