After Lightoom 6.3 update, lightroom won't open video files, won't import any files if any video file is present in the folder. Nothing else changed in the system, just lightroom 6.3 update. I been using lightroom since version 3, I installed every version, every update of lightroom since version 3, all version of 4, all version of 5. If you’re on Lightroom version 6 (the last perpetual version of Lightroom), your camera might be newer to where it’s not supported. For a complete list of supported cameras, visit the Adobe website. And if you are a Creative Cloud subscriber, you still might not have the most recent version of your Lightroom software.

Exact Lightroom Version (Help menu > System Info): LR CC Classic 7.0.1
Ok when I try and open a photo in PS through LR via the (open in photoshop cc option) Nothing happens. PS opens normally but then given me the regular open window in PS. Like if I were going to open a new file. Does anyone know what could be happening, did something move around in the last update? thanks in advance for any help.

When you launch Lightroom Classic, you encounter the error 'The Lightroom catalog cannot be opened because another application already has it opened.'

- Go to the folder where your catalog file [yourcatalogname].lrcat is saved. By default, Lightroom Classic saves catalogs in the following folders:
- Windows: Users[user name]PicturesLightroom
- Mac OS: /Users/[user name]/Pictures/Lightroom
where [user name] is the user id with which you are logged in. - Move the [yourcatalogname].lrcat.lock file to the Trash (macOS) or Recycle Bin (Windows), if it is present at this folder location.Caution:Do not delete or move the main [yourcatalogname].lrcat file.
- If your catalog opens successfully, you can empty the Trash (macOS) or Recycle Bin (Windows).

When Lightroom Classic is running with a catalog open, it creates a [yourcatalogname].lrcat.lock file next to the [yourcatalogname].lrcat file. This file ensures that there is no other access to the catalog in use. When you exit Lightroom Classic, the lock file is deleted automatically.
Adobe Lightroom Won't Open
However, if Lightroom Classic is not shut down properly, the .lrcat.lock file remains in the same folder as the .lrcat file, which prevents Lightroom Classic from opening.
