Hi I just updated to Lightroom Classic and when i am in my library view mode, I cannot organize my photos by name or type anymore ?
This is an essential part of my workflow.
Please post a screen shot here in your Library view with the entire screen showing. What happens when you change the sort order? Are your images stored on an external drive? Is the drive connected?
First try to deactivate the GPU support.
Another point is to reset the preferences.
If this doesn't help we need more informations about your system.
Which operating system do you use?
Is your system up-to-date?
