G7X problems with Image Sync

[Jeffieh]

Hi there.
I'm new here so apologies in advance if I've posted this in the wrong place.
I have a Canon G7X, which is a wonderful little camera.
Unfortunately, lately I haven't been able to upload pics using image sync or the Canon Image Library.
I've attached a sequence of phone photos so you can see where the process hits a snag - and for the record, the camera's date & time are correctly set.
If anyone can help me with this, I'll be very grateful!
Jeff
