Render a quiz

Hi! I have a problem with the quiz view. I have a custom theme that don’t let to Learnpress to render the quiz (I get a blank page) so I want to embed the quiz in a custom page instead.
How I do that? I tried to render the Backbone scripts but nothing happens. Can you help me? It’s the last step to finalize a project that I been suffering the whole year and I just want to… end it, please. Thanks!
