Your code is not clear, but I have upated it to correct some mistakes. Try this. 
public class EmployeeRelatedList {
 private Empolyee_Details__c empDetail;
 //private Apexpages.StandardController controller;

    
    public EmployeeRelatedList(ApexPages.StandardController stdController) {
        //controller = stdController;
        this.empDetail = (Empolyee_Details__c)stdController.getRecord();
        
    }
    
    public Pagereference save() {
​        try{
            if(empDetail.id == null){
                insert empDetail;
                return new Pagereference('/apex/Custom_pagenations'); 
            }  
            else{
                update empDetail;
            }
        }
        catch(Exception e){
            Apexpages.addMessage(new Apexpages.Message(Apexpages.Severity.ERROR, e.getMessage()));
            return null;
        }
    }
}
Hope this helps.

You have to add a return statement (return null) after the update empDetail (line 19).
