Why isn't my video displaying on Windows 10 edge/chrome but it on macOS chrome?

from running some tests I have noticed that my video within the “OUR PROCESS” section isn’t displaying properly on certain browsers.On [Windows 10 chrome/edge the video doesn’t display.][2] However, on macOS safari/chrome it does display. How can I get my video called “3434.mp4” to display on all browsers such as windows 10 edge and chrome.

Feel free to check out the code on the `index.html’ page or even other related files to help me find a solution. Thanks in advance. https://github.com/liamdocherty/car_detailing
