A recent batch of images is giving some trouble and DxO PhotoLab is unable to open some of the files saying they are corrupt or unsupported. However they open just fine with Sony Image Edge Viewer.
I have uploaded a sample RAW file with my username as the ticket number.
We had some issues with A1 in previous versions, so my first question - do you user the latest PL 4.3.1 build #4595?
And if you use the latest version and still have the issue, please, try to put this image in a new folder and then open it with PL.
