Final Cut Pro X 10.3 Quitting on Startup

I am experiencing an issue where (since the update, though that may not be related) every time I try to open final cut, I receive this message:

"The last time you opened Final Cut Pro, it unexpectedly quite while reopening windows. Do you want to try to reopen its windows again?

If you choose not to reopen windows, you may have to open and position the windows yourself."

Followed by the option to either "Don't Reopen" and "Reopen".

No matter which option I choose, it crashes on startup, and I receive the same message.

The problem started when I was attempting to import some .wav files into a new event. After selecting my files, I went to assign roles to them (God bless the roles system, it's beautiful). However, Final Cut, and my entire computer froze and became unresponsive.

After waiting about 10 minutes, to be sure it wasn't something that would resolve itself, I did a hard reset of the computer, and reloaded everything. It was when I first tried to open FC again that I received the first message, and now it's simply going through the same cycle over and over again.

I am operating this on the 2015 model of the 13-inch MacBook Pro.
