Recording issue ... Braw file incomplete

Hello,
Today I encountered an issue that I've never had before with my Blackmagic Cinema 4K camera.

I recorded an hour of video in .braw format, but when I tried to stop the recording, the camera froze.

I restarted the camera, and now my file is only 6 GB and lasts only 2 minutes.

I haven’t touched the drive since.
Do you have a solution to recover the data?

Thanks you for help
