That error indicates the camera doesn’t support the MPT-standard method of presenting a user-selected list of images to an MPT client like Airnef. Try using the “Select on Computer” method instead of the “Select on camera” method.

Don’t know how to edit the title, typo “Canon EOS 1300D”.
I tried select on computer now, there’s no error showing up and the airnef window just closes. Though I see a moment of screen going black on the camera when I press the button. Whenever I connect to the camera using Canon app on my phone , the screen goes black and when I disconnect the app screen comes back on. I think the same is happening with airnef but it is just connecting for a moment.
