You can try the following way:

view.py

@login_required  
def BlogLike(request, slug):
    post = get_object_or_404(BlogPost, slug=slug)
    liked = False

    if request.method == 'POST':
        if post.likes.filter(id=request.user.id).exists():
            post.likes.remove(request.user)
            liked = False
        else:
            post.likes.add(request.user)
            liked = True

    return HttpResponseRedirect(reverse('viewblog', args=[post.slug]))

and in html

{% csrf_token %}
<form action="{% url 'likepost' post.slug %}" method="POST">
  <button type="submit" id="like" value="{{ post.slug }}" class="btn btn-outline-secondary rounded-0 custom-button">
    {% if post.likes.filter(id=request.user.id).exists %}
      Unlike <i class="fa-solid fa-heart-crack"></i>
    {% else %}
      Like <i class="fa-solid fa-heart"></i>
    {% endif %}
  </button>
</form>
