Bridge quits unexpectedly

hello!

first time posting but so frustrated and have been googling like crazy. I recently updated my Mac retina to Mojave and since then everything has been SO painfully slow and bridge keeps shutting down and my Mac keeps restarting..:right in the middle of editing.

Then bridge termination reason is:  namespace SIGNAL, code 0xb

I have already uninstalled, restarted and reinstalled bridge but it’s still happening.

I am also not super techy so any help would be appreciated! Thanks!!
