Windows task scheduler with 2 xaml files in single project

I have 2 xaml files in single project. One is to get data from database Bday.xaml and another xaml file is to send email Sendemail.
I created bat file and started the Bday.xaml file as below
start “” /min “C:\Program Files (x86)\UiPath\Studio\UiRobot.exe” /file:“D:\PROJECTS\TFS Projects\RPA\HR-Email Notifier\B’day.xaml” /input:"{‘StartedByTaskScheduler’:true}"
Trying to schedule the task in windows task scheduler. Only the first xaml file is exectuting, the second xaml file called from first file is not hitting.
