OSStatus error -122: Operation couldn't be completed

To improve my understanding of the phenomenon, it would be highly beneficial if you could share a full screenshot (Do not crop it). Visual representations carry a greater impact than written descriptions.

Please remember that this is a public forum, so when attaching a screenshot, please avoid including any personal credentials such as IP addresses, card details, email IDs, Apple IDs, IMEI numbers, serial numbers, phone numbers, order IDs, or any identifiable location information if you are sharing a map.

With the limited information that you have provided, It is hard to even guess the problems faced by you.

Could you tell me where you see this error on your Mac or iPhone, and what you were trying to do when it appeared?

For example:

• Photos or Wallpaper: Adding a photo, creating Photo Shuffle, or applying a Depth Effect.
• Safari or iCloud: Importing bookmarks, syncing, or accessing files.
• Mac: Opening an app, copying files, or connecting a device.
• Another app or operation.

If you share the exact steps that trigger the error, someone can help narrow down the cause and suggest the appropriate fix rather than guessing at a solution.
