P: Unable to openHasselblad’s FFF format

I have same problem with file fff of my Hasselblad H6D 100, not possible open with new camera raw

I have the same problem. I have macOS Tahoe 26.4.1 and Lightroom Classic 15.3 and Camera raw 18.3.

Bonjour, depuis quelque temps, j’ai des problèmes avec les fichiers FFF de mon X2D Hasselblad. Aucun problème avec le fichier 3FR. Le fichier FFF est généré par le Phocus le logiciel d’Hasselblad quand je travaille en mode connecté. Le problème n’est pas seulement avec les nouveaux fichiers, mais aussi les fichiers déjà dans mon catalogue. J’ai un message qui me dit « Le fichier semble être endommagé ou ne pas être pris en charge ». Avant, il n’y avait aucun problème. Est-ce un problème de la dernière version de Lightroom Classic?

Dealing with the same issue. quite frustrating as I rely on lightroom classic for all my client work. 
Please resolve otherwise will need to consider alternative programs

There is an updated version of the 18.3 plugin to fix some other issues, but nevertheless it still may be worth a try:

Happened to me yesterday on a commercial photoshoot. I am tethering into Phocus, and then viewing files in Bridge and Photoshop – both were unable process the files, not even display previews. 
Thought its something with new Phocus update, reinstalled, different version, but no help – turns out that CameraRaw 18.3 somehow silently dropped / broke support for one of the best cameras in the world right now. Without warnings, mentions.

Tried to download previous version 18.2 but adobe dont provide any previous download links.

Its completely unacceptable.

Utter shame.

Also one thing: when I wanted to open the .fff file with ACR 18.3. out of my explorer/finder, it had the same error.

I will now work my way up through the various updates to see where the problem started. Also tethering not working with X2Dii either🙄

Same problem here, fff files unrecognised in Lightroom Classic 15.3  with Camera Raw 18.3. says not supported.

Greetings ​@Lo_Sa 

Do you have the ability to share with Adobe Engineering a couple of the files that indicate they are not supported? 

Share them with a standard sharing service and direct message me with the link if you can. 

Thanks!
