View native Mobile App QR code is not appearing in Mendix studio pro 8.13.0

Hello All, I am new in Mendix and trying to create a basic native mobile app first time. I have followed all the instructions mentioned in the documentation of the Mendix to start with it and downloaded “Make it Native” in my android phone but when I opened “View Native Mobile App” option in Mendix studio then its not showing the QR scan code .After that I tried with my system IP address along with port number 8080 to access the Mendix app in my phone but it is displaying the error that “Unable to load script.make sure you’re either running a metro server. Not sure what is going wrong here”.Please help!   Screenshots:
