Error element myRule_1_A1 (FlowRecordUpdate).
The flow tried to update these records: null. This error occurred: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY: convertToUSD: System.LimitException: Too many query rows: 50001. For details, see API Exceptions.​ 
rigger convertToUSD on Opportunity (before update){
     
  Try 
   {
   List<String> oppiso = new List<String>();   
   List<Id> oppid = new List<Id>(); 
   List<date> cdate = new List<date>();
      
   List<DatedConversionRate> DatedConversion = [SELECT isocode,startdate,ConversionRate FROM DatedConversionRate] ;
   
   Opportunity conopp = [select  CurrencyIsoCode,amount,closedate  from opportunity where id = :trigger.newmap.keyset() ];  
   
    for(Opportunity o : trigger.new) 
    {
     oppid.add(o.id);
     oppiso.add(o.CurrencyIsoCode);
     cdate.add(o.closedate);
    }
    
   Double cts = [SELECT ConversionRate FROM DatedConversionRate 
                 where isocode IN :oppiso and 
                       startdate <= :cdate 
                 order by startdate desc limit 1].conversionRate;
                 
                  
   for(Opportunity ops : trigger.new) 
   {
    ops.CURRENCY_RATE__c = cts;
    }
    
    }
    
  catch (Exception e)
{
  system.debug(e);
     for(Opportunity ops : trigger.new) 
   {
    ops.CURRENCY_RATE__c = null;
    }
  }  
}

Please suggest me how to fix this issue in code or process builder

Try this Sudhir,

rigger convertToUSD on Opportunity (before update){
     
  Try 
   {
       List<String> oppiso = new List<String>();  
       List<date> cdate = new List<date>();
      
        List<DatedConversionRate> DatedConversion = [SELECT isocode,startdate,ConversionRate FROM DatedConversionRate] ;
   
        Opportunity conopp = [select  CurrencyIsoCode,amount,closedate  from opportunity where id = :trigger.newmap.keyset() ];  
   
        for(Opportunity o : trigger.new) 
        {
         oppiso.add(o.CurrencyIsoCode);
         cdate.add(o.closedate);
        }
    
        Double cts = [SELECT ConversionRate FROM DatedConversionRate 
                 where isocode IN :oppiso and 
                       startdate <= :cdate 
                 order by startdate desc limit 1].conversionRate;
                 
                  
       for(Opportunity ops : trigger.new) 
       {
        ops.CURRENCY_RATE__c = cts;
       }
    }
    
    catch (Exception e)
    {
        system.debug(e);
        for(Opportunity ops : trigger.new) 
        {
        ops.CURRENCY_RATE__c = null;
        }
    }  
}

Thanks Deepak for you reply oppid which was unused int he code is causing the issue ?

No actually you querying record in loop with inner loop. So the apex has limitation it's retrieve only 50,000 record and your exception showing that it's retrieving 50,000 plus record. I just customize your code.And try to avoid inner loop in apex class.
