unable to import

"the import dialogue doesn't launch. when I try and import I get the error message : AgPathUtils.getStandardFilePath: can't create directory at: /Users/donalgraham/Movies. Error message = %@."

Some testing shows that when you open the Import window, LR automatically tests for the existence of /Users/<user>/Movies and tries to create it if it doesn't exist. 

That suggests that your LR still doesn't have Full Disk Access.  Triple-check that and reboot.

If that doesn't help, that suggests something screwy is going on with the folder permissions of /Users/<user>/Movies.  

Try creating /Users/<user>/Movies in Finder and restart LR.  Does the Import window now open?

I think Adobe should add this as a ‘sticky’ message at the top of this forum, because it is by far the most frequently asked and answered question. Apple changed the security requirements in MacOS Monterey. Go to MacOS 'System Settings - Security & Privacy' and add Lightroom Classic and Photoshop to "Full Disk Access". Click on the lock icon to unlock the settings, then click on the plus icon to add Lightroom Classic and/or Photoshop if it isn't already listed. If it is listed, then just enable the checkbox.
