Hi,

Opening a raw from finder opens RawTherapee, but the file doesn't open. MacOS 15.5, Apple Silicon

os: macOS

**Short description** Doesn't matter what the raw files is, or the type. I've tr…ied opening CR2, NEF, RawTherapee opens to the default state, and nothing happens. **Steps to reproduce** 1. Download latest RawTherapee from github releases page (or website, tried both). Unzipped and opened DMG. Dragged .app in to applications folder. 2. Opened RawTherapee from application folder to make sure it opens. 3. Closed RawTherapee 4. Double clicked a raw in Finder 5. RawTherapee opens, but the file doesn't open. **Expected behavior** Expect to see the raw file opened. **Additional information** * RawTherapee 15.2 * MacOS 15.5 * Apple M4 * Tried downloading the build from the website, and from github releases page * Sidenote, when attempting to use RawTherapee as an importer for Digikam, RawTherapee crashes **Screen recordings** Attempting to open from Finder: ![Image](https://github.com/user-attachments/assets/34aad5f2-9628-4d9e-88f2-33daa1704b61) Attempting to import raw using DigiKam: ![Image](https://github.com/user-attachments/assets/34caa743-c88a-452b-835b-dc1826b5f573) Error report from the DigiKam attempt: https://gist.github.com/Clam-/52408ac183a66516a321843d85a27782

Thanks

Yes, I could reproduce the bug with the 5.12 version (right-click Open With RawTherapee: launches RT but the file is not open).

Yes, this version opens the raw file for editing.
