... does not work in my current Lightroom Classic CC 7.5 (Camera Raw 10.5). Conversion process gets stuck and leaves a DNG file which is marked corrupt.
Uncompressed RAF from full format mode so long worked without any problem. Camera firmware is latest version.
I am using MacPro with macOS High Sierra 13.6. (latest version).
Anyone else with that observation - seems for me like a bug.
