Just a thought, during LrC version 13 there there was a transition to a version 2 of the Sync to Creative Cloud engine. Due to this event LrC version 14 is unable to open a Catalog created earlier than LrC version 13.2. To enable this to happen you have to first use LrC 13.2 to upgrade the Catalog. This may be causing the problem you are experiencing. For sync to Adobe Creative Cloud you need to be using LrC 13.3 or later. Have a look at the info at the link below for an understanding of what took place. https://www.lightroomqueen.com/whats-new-in-lightroom-2024-10/   ... View more

@Amy_dp201 , When LrC is opens a Catalog file it creates a LOCK file which prevents any access to the Catalog file. When you exit LrC normally the LOCK file is deleted automatically, however if LrC does not close normally like the crash you experienced the LOCK file will remain in place and prevent LrC from booting the Catalog file. On Windows the Catalog by default is stored in a folder called Lightroom located your user files > My Photos > Lightroom. The Catlog file has the name you have assigned ending with the extention .lrcat (LRCAT) the LOCK will have the same name but will have the extention .lrcat.lock. Go to the Lightroom sub folder on your system and if you find a LOCK file present delete it, insure you do not delete the Catalog file. Next double click on on the Catalog file with the extention .lrcat and they should boot LrC. ... View more

Lightroom Classic does not delete images from the SD card when you import from the card so if you use Copy as DNG to your computer you will experiencing what you say is happening. The original NEF will be on the SD card. In addition, as far as I recall there is an option at import to also copy to another location and this would capy the original NEF image. Its is a good option to retain a copy of your original raw files, it's the only way to work with them in your Camera Software, since it will not be possible with them in your Adobe DNG files.   ...

LrC is the continuation of the original Lr version 6. LrC is only available with the Adobe Photography Plan which has Photoshop, LrC and a new Lr (cloud version) images are stored in Adobe Creative Cloud with the info that is normally stored in the Catalog file. LrC works like the original Lr with the images and Catalog on your Computer. See the article available at the following link. https://www.lightroomqueen.com/lightroom-cc-vs-classic-features/ this will help you make an informed decision. ... View more

@NeilW2897 , If you have installed the latest version of Lightroom Classic which is LrC 14.2 you will not be able to convert your LR 6 Catalog, directly to LrC 14. There was a new sync version in LrC 13.3.  to the sync processing engine 2. Do the following install LrC 13.2 and open you Lr 6 Catalog, this will convert the Lr 6 then you can update LrC to version 14.2.   ... View more

@Printdevil , You stated " This problem also prevents me from opening several RAW files as one layered Ps file, which is something I do quite often, so this issue is really affecting my workflow." I am not sure what you do to achieve this a far as I am aware LrC does not work with layers.  Please explain how you open several raw files to Ps as layers? Do you do this directly with Ps? Ok I see there is an option available in the edit in option in LrC to " open multiple images as layers in Ps".  What happens if you choose that option do you get an error message?   ... View more
