Using Bootstrap 5 with Bootstrap Icons, I also enlarged the icon using font-size:1.5rem;
, but that broke the vertical alignment for the links (If you remove the styling you can see it's working again, need to be in Full Page mode)
I could not find the correct way to vertically align it again:
<link href="https://cdn.jsdelivr.net/npm/bootstrap-icons@1.10.2/font/bootstrap-icons.css" rel="stylesheet"/>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/js/bootstrap.bundle.min.js"></script>
<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/css/bootstrap.min.css" rel="stylesheet"/>

<ul class="navbar-nav ms-auto me-4 my-3 my-lg-0 text-center d-flex align-items-center">
<li class="nav-item"><a class="nav-link me-lg-3" href="#">Menu Item #1</a></li>
<li class="nav-item"><a role="button" class="nav-link me-lg-3"><i class="bi bi-stack-overflow" style="font-size:1.5rem;"></i>Menu Item With Icon</a></li>
<li class="nav-item"><a class="nav-link me-lg-3" href="#">Menu Item #3</a></li>
</ul>

</nav>
Try adding the "d-flex" and "align-items-center" classes to that nav-link:
<link href="https://cdn.jsdelivr.net/npm/bootstrap-icons@1.10.2/font/bootstrap-icons.css" rel="stylesheet"/>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/js/bootstrap.bundle.min.js"></script>
<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/css/bootstrap.min.css" rel="stylesheet"/>
