So I had a similar problem. Every time I clicked on a property modifier or other tables, CK immediately crashes! After "some time" on google I found this out. ---->If your using a drawing tablet or something similar, disconnect it. Such a simple thing made the CK completely useless to me and apparently others. I found this out from smkie in the bethesda community here https://community.bethesda.net/thread/65191?start=0&tstart=0 Hope this helped for you too.
