If that uses a Bluetooth connection, it's probably the same issue that has broken the Fuji app connections on phones.

Hi, ever since I updated the firmware on my Fuji X-T5, I haven’t been able to connect it to my CamRanger 2 transmitter. I’ve already tried resetting both devices, but that didn’t help. Has anyone else run into this issue? Thanks

Hello, I am in France

Sorry to hear of no response. If you don't mind me asking what country are you in?  Cheers  Ian 

Doesn't look good - maybe you could contact the FujiFilm support group in France and ask them - they might also be able to estimate a repair cost.
