Since the upgrade to 12.3.1, only Finder sees folders on external SSD.
Neither iMovie nor any Adobe programs or Nikon NX are able to read any data from the drive.
A normal external HDD is fine though, reading all the sub-folders.
Any advice?
Hello philfrompretoria,
Thank you for posting to Apple Support Communities.
If you’re experiencing issues with your iMac, often updating will help resolve this. Here's how to complete this:
Before you get started, it's a good idea to back up your Mac. Then follow these steps to find and install any available software updates or upgrades.
1. From the Apple menu in the corner of your screen, choose System Preferences.
2. In the System Preferences window, click Software Update.
If your System Preferences doesn't include Software Update, learn how to upgrade to macOS Monterey or upgrade to an older macOS, and use the Updates tab of the App Store app to get app updates.
3. Click Update Now or Upgrade Now:
Update Now installs the latest updates for the currently installed version, such as an update from macOS Big Sur 11.5 to macOS Big Sur 11.6.
Upgrade Now installs a major new version with a new name, such as macOS Monterey. Software Update shows only upgrades that are compatible with your Mac.
This information is provided in Update macOS on Mac.
When this is complete, please test and report back with the result.
Cheers.

Hi Luis,
The SSD is connected via Thunderbolt 4 (USB-C) port and was accessible and working fine before the software upgrade from OS Monterey 12.0.1 to 12.3.1
As I mentioned, Finder reads all the folders! Its only certain programs (Adobe Lightroom, Nikon FX, etc.) which see the Lexar SSD drive but doesn't open or read its folders!
As I said before, those programs may need to be given permission.
The Finder obviously has to have access to all files and folders, but other programs may not.
In recent versions of macOS there has been a tightening of security.
If you don't give permission for an application to access folders in your external drive, it will behave the way you describe.
Go to System Preferences->Security & Privacy->Privacy, click "Full Disk Access" and add, say, Lightroom to the list, and test.
Here is how it looks (I don't have Lightroom, so my screenshot is for Final Cut Pro; if I uncheck it or if I remove it, the FCP will not be able to access external drives - same with Lightroom and others):
notice a new update OS Monterey 12.4 is now available. Maybe I should try installing it??
Thanks for your response.
However, my Macbook Pro 16 came with macOS Monterey ver 12.0.1 pre-installed and everything worked fine.
The problem started after installing the latest OS Monterey 12.3.1
When checking for updates now, it returns with my mac is up to date!
That was a minute ago!! When I just checked again, I see there's a new update 12.4 available.
I'm uncertain about upgrading again due to possible new issues??

And yes, you can try updating to 12.4, but see my previous post (and do a backup first; always have an up to date Time Machine backup before updating, in case anything goes wrong, like the new version introduces a showstopping bug - it can happen).
I have updated to 12.4 without any problems so far.
How is the SSD formatted and connected to your mac?
Also: check that these applications all have "Full Disk Access" in System Preferences->Security & Privacy->Privacy.
Thanks Luis, I added those programs to the 'Full disk access' and also opened 'Files and Folders' in the box underneath and access is back! Thanks so mush for your time and inputs. Appreciated!
Phil
