Hello ,

Run the below logic in before insert context

public class LeadTriggerHandlerService{
    public static void updateOwnerOfLeadFromDomain(List<Lead> newList){
    Set<Strig> setDomainName = new Set<String>();
    Map<String,String> mapLeadDomainToLeadOwnerId = new Map<String,String>();
        for(Lead objLead:newList){
            setDomainName.add(objLead.Domain__c);
        }
        
        for(Lead objLead: [SELECT Id,OwnerId,Domain__c FROM LEAD WHERE Domain__c IN: setDomainName ORDER BY LastModifiedDate DESC]){
            mapLeadDomainToLeadOwnerId.put(objLead.Domain__c,objLead.OwnerId);
        }
        
        for(Lead objLead:newList){
            if(mapLeadDomainToLeadOwnerId!=null && !mapLeadDomainToLeadOwnerId.isEmpty() && mapLeadDomainToLeadOwnerId.containsKey(objLead.Domain__c)){
                objLead.OwnerId = mapLeadDomainToLeadOwnerId.get(objLead.Domain__c);
            }
        }
    }
}
