I'm a Lr user for many years and for the first time I'm really disappointed with the latest as I cannot work with this tool anymore. In Library mode I see no issue but when switching to Develop mode the image in not shown anymore in the center window. I cannot edit it. A showstopper. Sometimes everything becomes black, sometimes it crashes. I don't know anymore how many crash reports am I supposed to send to get some attention. I use Windows 10.
