I'm struggling to upload users to my user Database on Access

Question

I'm trying to save users into my user database on access and I'm met with this error every time

net.ucanaccess.jdbc.UcanaccessSQLException: UCAExc:::5.0.0-SNAPSHOT user lacks privilege or object not found: USERS

I've insured there are no syntax errors in the code or Query I hope someone could help me sort this out

here is the class

public void UserUpload(RegisterUserModel registerUserModel) throws Exception
        {
    
         try
            {
             Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
             conn = DriverManager.getConnection(URL);
             Statement s=conn.createStatement();
             String sql = "INSERT INTO Users (Firstname, Surname, Email, Password) VALUES ('" +RegisterUserModel.name  + "','" + RegisterUserModel.surname + "','" + RegisterUserModel.email + "','" + RegisterUserModel.password + "')"; 
             s.executeUpdate(sql);
             while(rs.next())
                    {
                        System.out.println(rs.getString(1));
                    }
            } 
         
            catch(SQLException e)
             {
             e.printStackTrace();
             }
         
        }
 

        
public void update(String ud)throws Exception
{
    try 
        {
        Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
        statement = conn.createStatement();
        statement.executeUpdate(ud);
        }
        catch(SQLException e)
            {
            System.out.println("Cannot updte the database");
            e.printStackTrace();
            }
