Did I break my team project?

I am working in a very large team project. I'm on a Mac Pro  (Late 2013) 10.11.6 - 3.5 GHz 6-Core Intel Xeon E5 with 32 gigs of RAM.  Premiere Pro v 12.1 (we were having too many problems in the current version and rolled back one).

I was working in a sequence where I had a one and half hour multicam clip with 12 tracks of audio. I went through and created about 80 story and broll selects from it. So the timeline has one long multi-cam clip and about 80 subclips of b-roll and story selects from it. I then started editing these into a sequence with copy paste  - I was fairly well along so I probably added another 30 clips to that timeline.

The whole thing was incredibly sluggish, I thought why don't I move the original multi-cam clip and my selects into a new sequence in a  new bin and delete it from my working sequence.

So I lassoed all the clips I wanted moved and dragged them to a new bin, erroneously believing I would be creating the new sequence there.

It started populating the bin with all my individual clips and eventually it gave a force quit error, application not responding. I force quit out and now I can't get back into the team project.

HELP!

Another question - If I'm launching a Team Project and I have the Force Quit box open while it's attempting to load the Team Project, will the force quit box say application not responding while it is Preparing Team Project for editing (waiting)?
