Video files won't transfer

[JOOI]

Hi all. 

I usually shoot photos with my a7cii for my son's sporting team. For the tournament this past weekend the boys requested video. Now I have a full day of sporting video files that cannot be offloaded to use. I have recorded all files in XAVC S HD, 25p, 50M 4:2:2 10bit.  I can playback files on camera without issue. They show on Sony's Creator App on my iPhone but state an error as pictured. The files show on SD card .mp4, however they will not transfer to my MacBook without mention the problem, nothing happens. iPhone IOS is 18.5 and MacBook is running Sequoia 15.5, if that makes any difference. 

I would appreciate any assistance or guidance please. I really hope there is a way to get these files off camera.

Remove the card, insert it into a card reader, connect to the computer, and drag and drop the file to a new folder. This is how I upload all of my files; I never do it from the camera.

Thanks for your help.

I had tried this way as well with no luck, but I have got somewhere since writing this post.

I installed new codecs to my laptop and can now transfer them and view them on VLC player but they will not import into photos app or iMovie. 

Can I ask what you use for movie editing?

(I had always been able to transfer movies via the Creator App prior to this full day of recording video and then could edit in iMovie. Cannot understand what has changed.)

I don't do much with video, when I do I use Shotcut. I don't understand why drag and drop wouldn't work without a codec. I can understand not being able to view them, but drag and drop shouldn't be affected.
