P: Unable to Import Photos into new catalog without crash

Yesterday I "upgraded" to the Lightroom Classic CC version. I began trying to import some photos into my library and each and every time it crashes after a little while and doesn't actually import them.

I thought I would start a new catalog, to see if there was something incompatible or wrong with my previous library, however that too crashes. I can import about 2-3,000 photos and then each and every time I go to import a new folder of images -- bam.  

I've tried importing small batches, also crashes. 

Extremely disappointed!
