That is a "Divide by Zero" error, you'll need to add an escape/exit like this
IF(PARENTGROUPVAL(RowCount, Opportunity.SDR_Created_override__c, Opportunity.First_Meeting_Date__c) = 0, NULL,
(RowCount /
PARENTGROUPVAL(RowCount, Opportunity.SDR_Created_override__c, Opportunity.First_Meeting_Date__c))
)
