Manipulate Records with DML (Trailhead Challenge)

Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.NullPointerException: Attempt to de-reference a null object

I have written this code:-

public class AccountHandler {
    public static Account insertNewAccount (String name){
        Account a = new Account(Name = name);
        try
        {
            insert a;
         } catch (DMLException e) {
            return null;
            }
        {
            return a;
        }
        
    }
}

Still I am getting below error:-

Hi Rajeev ,
below code working fine for me : 
public class AccountHandler
{
    public static Account insertNewAccount(string name)
    {
        Account a=new Account();
        a.Name=name;
        try{
            insert a;
        }
        catch(Exception e)
        {
            return null;
        }
        return a;
    }
}
, if you still getting same error then check if there any active triggers on account object, if yes then inactive those triggers, and validate again

Thanks
