Error: "context must be a dict rather than set"

I started learning Django and got stuck. I am facing this error and I am at a loss as to what the issue is. The view on which this issue occurs (UserFormView) is already returning a dictionary.

Error Log:

TypeError at /music/register/

context must be a dict rather than set.

Here is my views code:

from django.views import generic
from .models import Album
from django.shortcuts import render,redirect
from django.contrib.auth import authenticate,login
from django.views import generic
from django.views.generic import View
from django.views.generic.edit import CreateView,UpdateView,DeleteView
from django.urls import reverse_lazy
from .forms import UserForm   

class IndexView(generic.ListView):
    template_name = "music/index.html"
    context_object_name = 'all_albums'
    
    def get_queryset(self):
        return Album.objects.all()

class DetailView(generic.DetailView):
    model = Album
    template_name = 'music/detail.html'

class AlbumCreate(CreateView):
    model = Album
    fields = ['artist','album_title','genre','album_logo']

class AlbumUpdate(UpdateView):
    model = Album
    fields = ['artist','album_title','genre','album_logo']

class AlbumDelete(DeleteView):
    model = Album
    success_url = reverse_lazy('music:index')

class UserFormView(View):
    form_class = UserForm
    template_name = 'music/registration_form.html'

    def get(self,request):
        form = self.form_class(None)
        return render(request, self.template_name, {'form': form})

    def post(self,request):
        form = self.form_class(request.POST)

        if form.is_valid():
            # clean data
            user = form.save(commit=False)
            username = form.cleaned_data['username']
            password = form.cleaned_data['password']
            user.set_password(password)
            user.save()

            # return user if the data entered is correct
            user = authenticate(username=username, password=password)
            if user is not None:
                if user.is_active:
                    login(request, user)
                    return redirect('music:index')

        return render(request, self.template_name, {'form', form})

Any help would be appreciated. Thank you.

You missed the colon after form

Try this:

return render(request, self.template_name, {"form": form})
