Hi Sweta,

You can try below sample code.
  
public class deActivateUser{

 public static void deActivationMethod()
 {
   List<user> allUser = [SELECT Email,Id,IsActive, UserRoleId, UserRole.Name FROM User];
   
     for(User u: allUser )
    {
     if(!Pattern.matches('[a-zA-Z0-9._-]+@[a-zA-Z]+.[a-zA-Z]{2,4}[.]{0,1}[a-zA-Z]{0,2}', u.email))
      {
        u.invalid_email__c = true;  
        u.IsActive = false;
        allUser.add(u);
      }
      
     } 
     update allUser;
     }
  }
  
trigger checkUserEmail on User (before insert, before update) {

 deActivateUser.deActivationMethod();

}

Also there is a simple way to export all the users via dataloader and then change the active field to false and upload using dataloader.
