Execution of AfterInsert caused by: System.SObjectException

I am getting below exception

Execution of BeforeInsert caused by: System.SObjectException: DML statement cannot operate on trigger.new or trigger.old: Class

I create a class which insert task for account object while creating task for a Lead object, below i hardcoded the account whatId. I created trigger for Task and call CreateTaskInAccount.createTask() from trigger, but its not happening like so.

Please share your feedback.

public class CreateTaskInAccount

{

 public void createTask(List<Task> TaskFromTrigger)

  {

  

    Account targetWhatId= [SELECT a.Id FROM Account a where a.Name='NishantAccount'];

    

    List<Task> tskList= new List<Task>();

    

    for(Task varTask: TaskFromTrigger)

    {

      Task tsk= new Task();

      

      tsk=varTask;

      tsk.WhatId=targetWhatId.Id;

            

                  

      tskList.Add(tsk);

    }

  

    Database.Insert(tskList);

  }

}

------------------------------------

trigger CreateTaskInAccount on Task (before insert, before update) {

  List<Task> lTask = new List<Task>();

  

    

  CreateTaskInAccount objAccount=new CreateTaskInAccount();

  objAccount.createTask(Trigger.new);

}

Tanks in advance

    Please use before insert Trigger :-

     

    trigger CreateTaskInAccount on Task (before insert) {
      List<Task> lTask = new List<Task>();
      CreateTaskInAccount objAccount=new CreateTaskInAccount();
      objAccount.createTask(Trigger.new);
    }

    Apex class like below

    public class CreateTaskInAccount
    {
    	public void createTask(List<Task> TaskFromTrigger)
    	{
    		Account targetWhatId= [ SELECT Id FROM Account where Name='NishantAccount' ];
    		for(Task varTask: TaskFromTrigger)
    		{
    			varTask.WhatId=targetWhatId.Id;
    		}
    	}
    }
