Problem importing DJI footage into Premier Pro CC v14

The import of DJI drone footage into Premier Pro has always worked without any issue for me, until recently. I shot some drone footage on the 16th June 2020 and the footage would not import and I got an error saying the files were damaged. This was the case with all the files and a bit worrying after a days filming.

The only thing I could thing of that had changed was the introduction of hardware rendering in Premier Pro.

I turned off GPU rendering and then found the files would import as usual without an issue and that GPU rendering could be turned on after import, also all the files now import without issue whether GPU rendering is enabled or not.
