LR CC crashes Mac Os Sierra frequently after finished migration of large catalog

just wanted to put this out there...i just migrated a 100 000+ image catalog into LR CC, images are uploading to cloud right now...

something must have gone strange, several crashes/kernel panics this morning, all only when running LR CC....

problem seems to be resolved now by un-installing and re-installing LR CC, i left all prefs intact.....

this is literally the first time in years that an app crashed my mac...running Sierra 10.12.6 right now...
