By “everything is clear,” you mean you figured out what you were doing wrong? You were loading Bootstrap-4 V4.6.0 CSS along with two different Bootstrap JavaScript files, V4.3.1 and V4.6.0. And your navbar code is from Bootstrap-5. If you want to use Bootstrap-4, get the sample template and navbar and use that as your starting point. — Rich DeBourke, Apr 19 '21 at 09:22

Can you please check the below code? Hope it will work for you. You are using Bootstrap 4 and therefore you require data-target and data-toggle attributes for your button navbar-toggler because you have used data-bs-target and data-bs-toggle attributes in the button which are bootstrap 5 toggle attributes.
