Since upgrading to Catalina, LR no longer recognizes Fuji Xpro 2 camera for import
Most likely this is not a Lightroom problem but a MacOS / Fujifilm problem. The camera may not be seen at all (so Image Capture would also not see it). Like Victoria suggests, an option is to use a card reader rather than connecting the camera to the computer via USB. This is also quite a bit faster usually, so it's always a good idea to do that.
