C M Y Lines across PSD Files imported on LR Classic

One possible answer is that: 

In order to import a PSD into Lightroom Classic, it must be saved in Max Compatibility mode - meaning it has a flattened layer baked into the top of the file to composite the various layers into an image Lightroom Classic can understand. PS ignores this composited layer and renders based upon the individual layers rather than the top version that Lightroom can read. 

To test if this is the issue, close Lightroom. Open the Image in PS. Save As and give it a new file name. Import this new file into Lightroom and see if the CYM Stripes persist in the newly created version and that they are in the same spots. If they do, the problem is elsewhere; if they do not, then the Max Compatibility portion of your PSD was corrupt. 

Hi @JOSE PABLO3014471655v9! Welcome to the community, and thanks a lot for sharing those screenshots—it really helps.

Quick question: are those three photos the only ones showing this issue, or have you noticed the same thing happening with others too? If you remove them from the catalog and try re-importing them, do the visual artifacts still appear? Are the lines still there even after exporting?

Appreciate your help as we look into this!

This is either a bad GPU driver or a corrupted file.

Corrupted files are caused by hardware malfunctions somewhere in the chain of usage of the file: camera card, USB port, hard disk, memory and probably a few other things. Try importing using different hardware, try a different camera card, etc.
