I'm unable to Run powershell script from Asp.net core mvc

Question

Error: System.Management.Automation.PSSecurityException: 'File C:\Anand\VS_Projects\FieldService\FieldService\wwwroot\Script_Files\ClearSpaceScript.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https://go.microsoft.com/fwlink/?LinkID=135170.'

I'm able to run this script file in this pc in Powershell ISE, but ASP.net is unable to run scripts.

This is my code:

            //Running Script  
            String r = "";  
            string SCRIPT_PATH = @"C:\Anand\VS_Projects\FieldService\FieldService\wwwroot\Script_Files\" + script.Location;  

            Runspace runspace = RunspaceFactory.CreateRunspace();  
            runspace.Open();  

            //create a pipeling and feed it the script text  
            Pipeline pipeline = runspace.CreatePipeline();  
            pipeline.Commands.AddScript("Set-ExecutionPolicy Remote-Signed -Scope Process");  
            Command command = new Command(SCRIPT_PATH);  

//Adding Parameters to the Powershell Script
if (script.isUsername)
{
command.Parameters.Add("username", username);
}

            if (script.isPassword)  
            {  
                command.Parameters.Add("password", runScriptModel.Password);  
            }  

            if (script.isUserPCName)  
            {  
                command.Parameters.Add("pcname", runScriptModel.Hostname);  
            }  
            pipeline.Commands.Add(command);  

//Running
try
{
var result = pipeline.Invoke();

                if (pipeline.HadErrors)  
                {  
                    var pipelineErrors = pipeline.Error.ReadToEnd();  
                    foreach (var error in pipelineErrors)  
                    {  
                        r = r + "@" + error.ToString();  
                    }  
                    r = r.Replace("@", System.Environment.NewLine);  

                    return Json(new  
                    {  
                        success = false,  
                        responseText = r  
                    });  

                }  

                foreach (var res in result)  
                {  
                    r = r + "@" + res.ToString();  
                }  
                r = r.Replace("@", System.Environment.NewLine);  

                return Json(new  
                {  
                    success = true,  
                    responseText = "Script finished Running",  
                    result = r  
                });  
            }  
            catch (Exception ex)  
            {  
                ViewBag.Result = ex.Message;  
                return Json(new  
                {  
                    success = false,  
                    responseText = ex.Message  
                });  
            }
