Not able to upload images in LR classic v15.0.1
I have uploaded over 100k images over the years using LR classic and my card readers and CR2 files. As of last week LR shows the card reader and the card but produces not images to upload. I run windows 10, and have made no software changes except for the upload of v15.0.1. I'm not talking about syncing with the cloud or across any additional apps. I just can't upload my images. I know they are there, as I can see them on explorer, so the card isn't corrupted. This has not happened with SD and CF cards. Additionally my friend reports he is also unable to upload CR2 images through bridge/camera raw. Help?
