Elements 10 Organiser Not Working

Hi - I am not able to use the Downloader for getting media from camera/folders. Downloading from a folder results in the message 'Organiser has stopped working' with an option to close the program. Downloading from camera results in Error Code c0000005/6cc6346b.

I have run the sfc/scannow tool, re-installed Elements 10 and reset Preferences to defaults.

I don't know if this is relevant but the problem may have started when I downloaded photos from iPhone. I opted out of using Elements 10 to load the photos as  I wanted to load them via Windows - maybe disabled something in Elements 10 as a result ?

Thanks for help.
