Vertical lines on photo post processing with DXO3

Am using a canon R5 with RF 100-500 lens
Vertical lines are visible on the photo post processing with DXO PureRaw 3.
What is the reason for this?
This happened only after I purchased an upgrade from 2 to 3
Did not happen with the trial version of 3
What can I do to correct this problem?


Can you share a screenshot that shows the problem?
