downloading zero byte file name prelanding on Safari browser

I am been observing a weird issue when logging into the Office.Com Business account on the Macbook using Safari. As soon as I login or go to the dashboard, there is a file that's getting downloaded named "prelanding".

Intrestingly this prelanding file is empty, of zero bytes. downloading prelanding file empty

This file has no extension and is 0 bytes in size.

Is anyone facing this issue? Seems to be specific to macOS and Safari Web Browser!
