My github repo is not showing the language statistics [in the form of the bar under 'packages'] and the most used language. I've done some testing with the same files and it seems like Github's Linguist just starts to break after a couple of commits. I've also looked into problems that might arise with vendored code and stuff like that but it doesn't seem likely since all the files worked when I tested them individually. I just don't understand why it breaks and then doesn't work again.
Here's a link to the repo: https://github.com/arshb22/Virtual-Reality-and-Game-Design
It seems that your repo is filled with files that have extensions that Github doesn't recognize. If your files don't have extensions used by common programming languages, Github won't be able to label them since it doesn't know what they are.
