I do have an update! Unfortunately, due to the nature of your crashes, it requires a patch (and cannot simply be updated via the backend, which does not require a patch). The patching process is quite lengthy for console (compared to Steam), so I predict the patch will be released during the week beginning the 20th, however I cannot say this with complete certainty right now. 
Please accept our apologies for the inconvenience, I completely understand how this could sour your experience especially as new players. Of course, if you would rather opt for a refund, please explain your issue to Microsoft Support who will be happy to help with that.
