This is my apex class:

   global without sharing class VF_DeleteOpenTimeSlotsBatch      implements Database.Batchable<sObject>,Schedulable,database.stateful  {
    Set<Id> deleteTSIds;// = new  Set<Id>(); 
    
    global VF_DeleteOpenTimeSlotsBatch(Set<Id> setTSIds){
        deleteTSIds = setTSIds.clone();
    }
    global void execute(SchedulableContext SC) {
        VF_DeleteOpenTimeSlotsBatch schdVar1 = new VF_DeleteOpenTimeSlotsBatch(deleteTSIds); 
        
    }
    

    //Start method
        global Database.QueryLocator start(Database.BatchableContext BC){
        //fetch the field values
        System.debug('check for'+deleteTSIds);
        String queryString ='SELECT ID from VF_TimeSlots__c WHERE ID IN: deleteTSIds';
        return Database.getQueryLocator (queryString);
    }
    
    //Execute method
    global void execute(Database.BatchableContext BC, List <VF_TimeSlots__c> timeSlotsList){
        System.debug('timeSlotsList'+timeSlotsList.size());
        delete timeSlotsList;
    }
    global void finish(Database.BatchableContext BC){
    }
}
