Lightroom Classic will not import after newest update - the photos will import to Lightroom CC, but not to Lightroom Classic. It stays on the "importing...." screen.
I've not had this issue yet but a walk around in the meantime may help until this bug is fixed. Create a new folder on your hard drive and drag the files from the memory card into that new folder then in lightroom, add that new folder to the catalogue. As dmeephd mentioned above.
