Generate image with firefly image 5 is not working but it is working for others models

I’m facing an issue while using the Adobe Firefly Image 5 model for image generation. The same prompt works correctly with other models (like google banana etc.), but when Image 5 is selected, the generation fails and no image is produced. I have tried multiple prompts, different browsers, and different sessions, but the issue is consistently reproducible only with the Image 5 model. This is blocking me from testing or using this model

prompt below-

Female:

Use the uploaded image as a STRICT identity reference.

FACE LOCK — CRITICAL:
•⁠ ⁠The face must remain EXACTLY the same in all 9 tiles•⁠ ⁠Same facial structure, same eyes, nose, lips, jawline
•⁠ ⁠Same expression, same head angle, same camera distance
•⁠ ⁠NO face beautification, reshaping, aging, or gender changes

INTERNAL ANALYSIS ONLY (do NOT output text):
Analyze the uploaded face to determine:
•⁠ ⁠Face shape (jawline, cheekbones, forehead ratio)
•⁠ ⁠Hair density, natural texture, curl pattern (1A–4C), porosity
•⁠ ⁠Natural parting and growth direction

FINAL OUTPUT — IMAGE ONLY:
Generate ONE single vertical 9:16, true-4K image containing a 3×3 grid of FEMALE hairstyles applied realistically on MY FACE.

GRID REQUIREMENTS:
•⁠ ⁠9 UNIQUE female hairstyles
•⁠ ⁠Hairstyles ONLY change — NOTHING else
•⁠ ⁠Same lighting, same background, same pose across all tiles
•⁠ ⁠Maintain exact facial identity in every frame

HAIRSTYLE VARIATION RULES:
•⁠ ⁠Mix short, medium, and long female hairstyles
•⁠ ⁠Include professional, college, and youthful/teen-appropriate looks
•⁠ ⁠Examples of variation (do NOT label):
•⁠ ⁠Bob / Lob
•⁠ ⁠Layered medium cut
•⁠ ⁠Long straight or soft waves
•⁠ ⁠Shoulder-length with curtain bangs
•⁠ ⁠Low-volume professional styles
•⁠ ⁠Youthful modern feminine cuts
•⁠ ⁠Respect my real hair texture and density
•⁠ ⁠Natural hairlines, realistic scalp visibility
•⁠ ⁠No fantasy volume, wigs, or over-styled AI hair

TECHNICAL REQUIREMENTS:
•⁠ ⁠Vertical 9:16 composition
•⁠ ⁠True 4K clarity
•⁠ ⁠Natural lighting (studio or daylight)
•⁠ ⁠Realistic hair movement and shadows
•⁠ ⁠Photorealistic skin and hair texture

ABSOLUTE RESTRICTIONS:
•⁠ ⁠NO text
•⁠ ⁠NO captions
•⁠ ⁠NO explanations
•⁠ ⁠NO labels
•⁠ ⁠NO background changes
•⁠ ⁠NO makeup changes unless already present

GOAL:
Create a professional female hairstyle reference grid where ONLY the hairstyle changes and the face remains perfectly identical.
