Navbar Won't collapse on mobile version-CodePudding

Navbar doesn't drop down and show the options on the mobile version. I am trying to figure out how to get it to work, but no luck.

Also ms-auto doesn't seem to work either, and when I try to change the size of the text, it refuses to grow past a certain point. Can I get help please? I've tried switching the order of the scripts that run, I've tried running it with JQuery, I've tried everything. The only time I see the options is when I use the container-fluid class, but since I can't hide the options when I do that on the mobile version, there's no point. How do I get this to work?

It is because you are still using classes from BS4. Try reading the docs of BS5 here.
