não consegui abrir a imagem

Error message

não consegui abrir a imagem: {}

What it means

Decode failure in icon_pack run: the user-selected image file could not be opened/decoded by the image crate (corrupt bytes, unsupported codec, or permission denied), so no icon variants can be generated from it.

Solutions

1. Re-export the image in a standard format (PNG/SVG rasterized to PNG)
2. Verify the file is not corrupt by opening it in an image viewer
3. Check file read permissions for the app process
