P: on macOS JPG export color issues

When exporting from Lightroom CC on macOS, the exported JPG takes on remarkably different colors (it looks like a lower/bluer color temperature, but I'm not precisely sure). The difference appears within the Lightroom CC export preview prior to exporting, as well as with the exported image when opened in other applications. Different images have different levels of impact, but I've seen visible differences in most of my images. The issue appears regardless of what Color Space is selected for the exported JPG.

I do not have issues when exporting the same image with Lightroom CC on iPad. I've tested by exporting the same image with the identical settings on iPad and the image is reproduced faithfully.

I'm running Lightroom CC Version 3.3 from the Mac App Store (20200611-1039-7df19f1 Build) on macOS 10.15.5 on a MacBook Pro (Retina, Mid 2012).

For reference, I posted some details, including these screenshots of the issue and exported images, in the Lightroom community thread Trouble exporting image with my edits thread. Another user reported similar issues in a Pink hue rendered upon export thread.
