Sorry for the dumb question, but are you executing this function from an Opportunity After Update Trigger?

Hi Akash,

Please try the below code:
  
public class DESC_UpdateForum {
    public static void DESC_UpdateForumMethod (list<Opportunity> Opplist){
        Set<Id> idSet = new set<Id>();
        For(Opportunity Opp : Opplist){
                idset.add(Opp.id);
        }
        List<OpportunityContactRole> conList = new    List<OpportunityContactRole>();
        conList =[SELECT Id,OpportunityId,ContactId FROM OpportunityContactRole WHERE OpportunityId in :idSet];
        system.debug('conliat------>'+conList);
        set<id> Idcon  = new    set<id>();
        for(OpportunityContactRole co :  conList){
            Idcon.add(co.ContactId);
        }
        List<Contact> coList = new List<Contact>();
        coList = [SELECT id,Description from Contact where Id in :Idcon];
         List<Contact> coList1 = new List<Contact>();
        for(Opportunity op : Opplist){
            for(Contact con : coList){
                con.Description = op.Description;
             coList1.add(con);
            }
        } 
        update coList1;
    }
}
//Trigger Class
trigger UdateContactDiscription on Opportunity (before update) {
    if(trigger.isUpdate){
        DESC_UpdateForum.DESC_UpdateForumMethod(trigger.new);
    }

}
