Lightroom Desktop: Magenta Cast when sending to Photoshop

The naming of the different Lightroom versions is extremely confusing.

The cloud version is called Lightroom Desktop, and the non-cloud version is called Lightroom Classic.

That thread is about magenta cast on exported images from version 3.3 of the Lightroom cloud version on a Mac, while your're on Windows with Lightroom Classic 11.2, and you're using Edit in Photoshop, not Export.

So you solved it by downgrading, did you install 11.1?

I suspect the real issue is the GPU driver, or possibly a defective monitor profile.

I suggest that you reinstall 11.2, then try to turn the GPU off. If that fixes the issue, see if there is an update for your graphics driver, run the update, then try to turn the GPU back on.

If that doesn't fix the issue, recalibrate, and make sure to create a version 2 (not version 4), matrix based (not table based) ICC profile.

Also bear in mind that Windows updates are known to install low quality profiles made by monitor manufacturers. These profiles are very often defective out of the box.
