Problems importing raw files from an external drive since update

[Kim27267947htqm]

I have copied my raw files to a folder on my external hard drive. Since the update, when I import it was changing them all to DNG files. I don't want that. I was able to fix that on the top bar of the import bar. I just want to add them to the catalog and then work on the files. But it won't let me add the files. I can only copy them to a new location. So - it's creating dated folders within my original files - thus taking up twice the amount space. Also - when I go back into LrC later, the folders are NOT in my catalog and I have to reimport them. Can someone please help - I am in my busy season and this is killing me.

If you haven't already done so, then you'll need to give LrC full disk access as described here https://community.adobe.com/t5/lightroom-classic-discussions/quick-tips-how-to-give-full-disk-access...

If above doesn't resolve the issue, then please submit your 'System Info' This can be copied from the Help > System Info menu option.

Is your MACOS  Ventura (13.x)?

if so

Is your catalog on an external hard drive?

and

LrC v12.0 or v12.0.1?
