Trying the load RAW images from my Canon EOS 5D Mark IV and all of a sudden Lightroom (on my Mac) is giving me the message "We're searching for images. This could take a while. You can wait, or cancel the import and try a different source. If you are importing from a phone, please make sure it's unlocked." It spins until my camera goes to sleep and then says "No images that can be imported were found in the selected source. If you are importing from a phone, please make sure it's unlocked." I have loaded RAW images in this way many times with no problems. Wondering if this is related to the most recent update? Any thoughts on how to resolve?
