List<Account> accList = [Select id,Name,(Select Id, name from Contacts) from Account where Id IN: accIds ];


for(Account acc : accList){
   for(Contact con : Trigger.New){ 
    if(acc.Contacts.size() == 5) {

    }

Hi  Yagna


in below line you need to add con instaed of acc
acc.addError(' You can not add more then 5 contacts');
  
for(Account acc : accList){
   for(Contact con : Trigger.New){ 
    if(acc.Contacts.size() == 5) { 
       con.addError(' You can not add more then 5 contacts'); 
    } 
 }    
}

Please double-check a few of the code's updated lines. I hope what I said about the comments being changed is accurate fnf mod (https://fnfmod.co). It prevents the creation of a new sixth record and instead throws an error rather than an error message.
