I just did the Monterey update because my Lightroom was very sluggish, even with doing a LR update. Once complete, I open LR and everything is running fast again. However, when I go to import photos from my SD card to my external hard drive as usual, I get an error saying that the files either can't be read or destination folder is not writable. The hard drive is not locked and is read/write available. I can open my SD card and see all my raw images. Any ideas on how to fix this?
