Trouble rendering first project in Premiere Rush

-1609760768

Clip is 16 seconds long. I wish to export in 1080p. Tried on two different devices now, one being a standard laptop and then now my desktop that should be better prepared for this type of work. 

I use premiere pro usually or imovie but downloaded rush for my partner who finds its easier. any tips on how to get it rendering? 

The time stamp says the problem is at 16 seconds. 

Edit: it will export/ render at 720p. The camera used is capable of 1080p.

THank you
