MC seems to be crashing when it hits one or more of your video files that it is trying to import. The one that's crashing it repeatedly appears to be:
/Users/laurenwhitaker/FrostWire/Torrent Data/The Intern 2015/The Intern 2015 1080p.wmv
Try moving that file to another directory where MC will NOT try to import it. Then launch MC. As Jim said, turning off auto import might be smart too, while you're getting started:
Tools > Options > Libraries & Folders > run auto import in background > (uncheck)
If you have many, many videos from umm... "various sources", you may find that you have 5, 6, 10, or more videos that will crash MC. Hopefully this will be the only one for now. If not, post a log again as you just did and we will try to help you.
Oh and it's not good to have MC trying to auto import from directories where video files are being written. You should be downloading or ripping videos to one or more outside folders. Then, once the video is *totally* complete, you move the video to a monitored folder where MC can then import it. MC wants to analyze the video when it does import, and it can't properly analyze a video that's only 10% complete (or even 90% complete for that matter).
Good luck.
