get_context_data does not work with a request parameter. You can pass an arbitrary number of parameters, but here your get_context_data will only run if it is called with the request. You access the request with self.request:

class RiskSet(SingleTableMixin, FormView):
    template_name = "risk/RiskSet.html"
    model = RiskSet
    form_class = RiskSetForm
    
    def get_context_data(self, *args, **kwargs):
        form = RiskSetForm(self.request.POST or None)
        if form.is_valid():
            form.save()    
        # Call the base implementation first to get a context
        context = super().get_context_data(*args, **kwargs)
        # Add in a QuerySet of all the books
        context['page'] = 'risk'
        return context

Furthermore it makes no sense to do this in the get_context_data method. A FormView has routines in place for this. It You can probably also work with a CreateView which will remove more boilerplate code, like:

from django.views.generic import CreateView

class RiskSet(SingleTableMixin, CreateView):
    template_name = "risk/RiskSet.html"
    model = RiskSet
    form_class = RiskSetForm
    success_url = 'path-to-url-when-form-is-valid'
    
    def get_context_data(self, *args, **kwargs):
        context = super().get_context_data(*args, **kwargs)
        # Add in a QuerySet of all the books
        context['page'] = 'risk'
        return context
