The 'Folder not found' error message closes automatically. In macOS 12, the "Server Settings..." sheet window automatically closes after interaction with it. This is not the case in macOS 15. Depending on the type of interaction, the follow-up dialogue box is also automatically closed.

Steps to reproduce:

• create a new server but do not initialize it
• open "Server Settings..."
• Click on "Show" for the "Data Directory"
  • the "Sever Settings" window closes, an dialog "Folder not found" appears and immediately closes again
• open "Server Settings..."
• click on "Change Password"
  • the "Sever Settings" window closes, an dialog "Could not get list of users" appears and stays open
