Quick summary

Imagen couldn't save your edits to the folder with your photos.

How to fix this

1. Make sure the folder isn't read-only, and that you have permission to change it.
2. Close other apps that have these photos open, like Lightroom Classic, Photoshop or Photo Mechanic.
3. Avoid cloud-synced folders (Dropbox, iCloud, OneDrive, Google Drive). Move the photos to a local folder if you can.
4. Mac: Make sure Imagen has access to your folders. Go to Apple menu › System Settings › Privacy & Security › Files and Folders, find ImagenAI, and turn on the folders. Then go to Full Disk Access, and turn on ImagenAI.
5. Windows: If Controlled folder access is on, Windows blocks apps from changing files in protected folders like Pictures, Documents and Desktop. Go to Windows Security › Virus & threat protection › Manage ransomware protection, select Allow an app through Controlled folder access, and add Imagen.
6. Click Try again in the message.
