Lightroom 6.8 repeatedly crashing with MacOS 10.13.1. Any ideas?

Any help from the forum would be appreciated!  I'm out of ideas and just want to process some photos...

Error message is

"lightroom quit unexpectedly"

I've tried everything I could find in the forum including:

removing/disabled all plug ins

tried safe mode

reset preferences

from terminal mode:
