When you click on a hamburger (three bars), the collapsed buttons do not open at a lower resolution, who knows what could be the reason?

I decided.
For some reason, the navbar-expand taken from the cheat sheet did not work for me ( https://bootstrap-4.ru/articles/cheatsheet/ ). A half-Internet break on the same site found a slightly modified code (I give an example below) and it all worked.
Example:
"

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-BS-toggle="collapse" data-BS-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarTogglerDemo01">
      <a class="navbar-brand" href="#">Hidden brand</a>
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>
