Hello Nagendra thank you for your help. Below is the code I have, but I'm getting an error that says: List has more than 1 row for assignment to SObject. Do you know what the issue could be? Thanks 

trigger OppOwnerUpdate on Opportunity (after insert) {
 
   if(trigger.isinsert){

       //opportunity IDs needed to update the owner value. These id records are shared by published company
       set<id> FinalOptyIds = new set<id>();
 
       //Collect the  list of opties which are created/updated by partnernetwork companY
       List<PartnerNetworkRecordConnection> ConListOpty = new List<PartnerNetworkRecordConnection>(
                                       [select Id, ConnectionId, PartnerRecordId, LocalRecordId from PartnerNetworkRecordConnection
                                               where LocalRecordId in :Trigger.newmap.keyset() AND (Status ='Sent' OR Status = 'Received') AND ConnectionId='007499281']);
       //system.debug('ConListOpty-----' + ConListOpty);
 
       //Collect the opty ids
       if(!ConListOpty.isEmpty()){
           for(PartnerNetworkRecordConnection op : ConListOpty){
               if(op.LocalRecordId != null){
                          FinalOptyIds.add(op.LocalRecordId);
               }
           }
 
           system.debug('FinalOptyIds-----' + FinalOptyIds);
 
           // Query the available opties which are shared by partner network
           list<opportunity> optyList = [select id,owner.id from opportunity where id IN:FinalOptyIds];
 
           list<opportunity> optyListFinal = new list<opportunity>();
 
                     //TODO: Opportunity Owner Move this hardcoding id to custom settings. change for each org when deploying
         Opportunity oppOwner = [select id from Opportunity where OwnerID = '00520000003p1tO'];
           //system.debug('optyList-----' + optyList);
 
           for(opportunity optOwner: optyList ){
               if(optOwner.Ownerid != null){
                   opportunity opty = new opportunity();
                   opty.id = OptOwner.id;
                  opty.OwnerId = optOwner.id;
                 optOwner.id = '00520000003p1tO';
                   optyListFinal.add(optOwner);
                   //system.debug('Done----');
               }
           }
    
           //TODO: Move this hardcoding id to custom settings. change for each org when deploying
          Pricebook2 priceb = [select id from Pricebook2 where id = '341393019'];
           //system.debug('optyList-----' + optyList);
 
           //updating the shared created opty owners with Opportunity product
           for(opportunity opt: optyList ){
               if(opt.Pricebook2.id != null){
                   opportunity opty = new opportunity();
                   opty.id = opt.id;
                   opty.Pricebook2ID = opt.Pricebook2.id;
                   optyListFinal.add(opty);
                   //system.debug('Done----');
               }
           }
           update optyListFinal;
       }
