Hi Jack,

You can use the below code.

I have written a trigger as per your requirement.  

<<<<<----Trigger ---->>>>> 
trigger ErrorMessage on Account (before insert) {
if(Trigger.isInsert && Trigger.isBefore){
    User_Account_Count.count_Account_Mounth(Trigger.new);
  }
}

<<<<<----Apex Class------>>>>>>
  
public class User_Account_Count {
    
    public static void count_Account_Mounth(List<Account> accListInsert){
        try{
            String userId = UserInfo.getUserId();
            List<Account> accList = new List<Account>();
            accList = [SELECT Id, Name FROM Account WHERE OwnerId =: userId AND CreatedDate = THIS_MONTH];
            System.debug('Account'+accList.size());
            if(accList.size() > 20){
                for(Account acc : accListInsert){
                    acc.adderror('Cannot insert morethan 20 account in a month');
                }
            }
        }catch(Exception exp){
            System.debug('Exception Cause---'+exp.getMessage() + 'Line Number---'+exp.getLineNumber());
        }
    }
}

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
