Hi,
Thank you for sharing your question. I understand how frustrating it is when a download freezes and continues processing even after you cancel it, especially when it restarts every time you open the app.
This behavior usually occurs when the application’s background tasks become stuck or when cached download data becomes corrupted, causing NX Studio to resume a process that can no longer complete. Restarting the computer alone often doesn’t clear this because the app stores its pending download queue inside its local cache or temporary workspace, which must be reset manually. Resetting the app’s temporary files, signing out of iCloud within the app, or removing the app’s background task folder typically forces NX Studio to stop the frozen process and start clean the next time you launch it.
To better guide you, may I ask whether NX Studio is installed on Windows or macOS, and whether you downloaded the iCloud photos through iCloud for Windows, iCloud Drive, or directly through NX Studio’s import tool? Once I know this, I can help you clear the stuck download safely and get the app working normally again. Feel free to follow up I’m here to help.
I hope this helps.
Best Regards,
Noel
