Ah yeah this ones a first, a lot of people who have the loading issues dont get past that.
I believe this is down to some issue, I originally thought hardware but that doesn't seem to be the case anymore. May I ask your CPU, GPU and OS? Trying to collect data on similar occurrences so I can try find what's causing this for people!
It's not a typical bug so I assume theres something causing an issue somewhere in that realm!
