I've tried redirecting, using other CDNs and other factors, but nothing works, none makes the collapse work. I would like some help as I have no idea why it is not working.
Who can help me and also explain why, I would appreciate it.


You have to change the data-toggle to data-bs-toggle and use data-bs-target attribute. Add the ID in the collapse div. That's all.
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#collapse" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="navbar-collapse collapse" id="collapse">

How to justify content on navbar (Bootstrap 5)

I currently have a very minimal navbar set up with Bootstrap 5.
With navigation bars, there is both the 'navbar-brand' and nav links.
I want my brand/logo to be all the way on the far left, while all the navbar-nav links to be all the way to the right.
This could be achieved with flexbox and justify-content-between
However I have 0 clue where the navbar flex properties come into play, so therefore I am not sure where or what to change to achieve this effect
<nav class="navbar fixed-top navbar-expand-lg navbar-light bg-light">
<div class="container">
<a class="navbar-brand" href="#"><img src="images/brand.png"></a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavAltMarkup">
<div class="navbar-nav">
<a class="nav-link active" aria-current="page" href="#">Home</a>
<a class="nav-link" href="#">About</a>
<a class="nav-link" href="#">Services</a>
<a class="nav-link" href="#">Contact Us</a>
</div>
</div>
</div>
</nav>

Is this what you want ? Indeed, justify-content-between is very useful for that. You have to use this style for the parent div and to put the children elements you want inside it.

Navbar when clicked is not redirecting to another page bootstrap 5

The issue is that when I click the navbar item it's not redirecting to the page and not giving any feedback. But when I delete the bootstrap.bundle.min.js it's working as it should be, but the expand button for the navbar when it's collapsed is not working.

The problem is the data-bs-toggle="collapse" data-bs-target=".navbar-collapse.show" on the navbar-collapse div. Remove it and the navigation will work fine.
<div class="collapse navbar-collapse flex-grow-1 text-right" id="navNavbar" data-bs-toggle="collapse" data-bs-target=".navbar-collapse.show">
<ul class="navbar-nav ms-auto flex-nowrap">

Also, jQuery is not required for Bootstrap 5

You made some mistakes in your code. Please check my code.
I am assuming you are using Bootstrap-5 where negative margins are disabled by default but can be enabled in Sass by setting $enable-negative-margins: true. Read their documentation - https://getbootstrap.com/docs/5.0/utilities/spacing/#negative-margin.
OR
use Bootstrap-4
OR
use your custom CSS.
Please check my code.

margin-left: auto;
