I was doing videos on my sony camera and all of them are in one file avchd WHICH is not possible to open by any program, even adobe encoder.
Is it possible it is too big file?
Which release/year of CC are you using? And what operating system version?
I too have this problem. And am looking for an answer. I even switched back to PrPro 2017 and it does import but doesn't pull any audio. I too have asked about this so if you want you can follow my question too and hopefully between these 2 post someone will have a solution.
Which operating system/version?
macOS High Sierra 10.13.4/CC 2018.
I now have installed CC 7.0 and it's working. It's not freezing on me and the audio is there.
