Hi Mikhail,
Sorry to hear about this problem. I have not run into it before. For Photos libraries, access to all images is through macOS itself. I imagine there might be some kind of cache that could be at issue. The simplest thing to do at this point is to remove a few files from the application’s sandbox folder. That should clear any stale data.
What the following steps will do is remove any Locations or Favorites that the application has remembered.
1) Quit the app if it’s running
2) Go to the Finder
3) Pick the Go > Go to Folder menu item
4) Paste this in and hit return:
~/Library/Containers/com.gentlemencoders.RAWPower/Data/Library/Application Support/
5) You will see a file called Locations.rpbookmarklist
6) Rename it (e.g., preface with a “-“ or something)
You can do the same thing for Favorites.rpbookmarklist and singleFileEditor.rpbookmarklist
7) Open the app.
If you add directories at that point, the app will make a new Locations.rpbookmarklist, etc.
If that does not help, then the preferences file could also be removed, but that can be step 2.
To remove the preferences file, you can do the following:
1) Quit the app
2) Go to the Finder
3) Pick the Go > Go to Folder menu item
4) Paste this in and hit return:
~/Library/Containers/com.gentlemencoders.RAWPower/Data/Library/Preferences/
5) Delete com.gentlemencoders.RAWPower.plist and 6MR872QP3J.RAWPower.sharedDefaults.plist.
6) Open the app
