Jpeg to RAW / vertical line artifacts

I bought Jpeg to RAW recently and I found the better the Jpeg input the worse is the outcome.
Really poor quality files gain from the procedure. But when I try to enhance good quality jpegs to RAW file the AI produce strange vertical lines. These outcome is not usable.

Any suggestions?

Use TIF rather than DNG and see if that makes a difference.

I tested both before I went to the community.

I had vertical artifacts when using Sharpen AI recently. When I went to submit a note to support, I read that I should restart computer after a software update. I did that and reprocessed an image that was bad. It came out fine.
