When you see the error “The selected image is either unavailable, in an unsupported format or corrupted.” in Capture One, it typically points to a system permissions issue, database inconsistency, or file location problem. Here’s how to troubleshoot it.

How To Fix
Most often, “unsupported file format” is due to lost access:
macOS may have revoked Capture One’s full disk access after the update. This can block file access and cause unexpected errors.
👉 Allow full access on macOS
What if I'm using Sessions?
Make sure you haven’t altered the internal folder structure of your Session — such as moving folders outside Capture One. If things look fine, verify your Session database.
