Strange color issues...

Just found this issue today. Using PS CC 2019, latest update. On Mojave, latest update.

So I was messing with a few images. Everything looked totally fine. I needed them for a website, so processed them up and saved them of as jpegs. Then later I wanted to make a larger image for a background for the website that was a collage of a number of images from the site. So I opened up the jpegs instead of the psd's due to the size of that many psd's being open at once might be a bit nuts...

Anyway, when I opened up the jpegs, from files that looked totally fine previously, the now looked crazy blown out colors. Everything had been set for Adobe RGB (1998) across the board, from the camera to the finished images. But jpegs that looked fine everywhere else that way, opening them into photoshop made them go crazy with the colors. Almost like the color was doubled up. I changed the color profile at that point to see what it did from Adobe RGB to just plain sRGB and they all looked significantly better in photoshop.

Saved things off again and looked at the images just in the previewer on the mac, as well as checking a few on the web after loading them to the website. The newly saved images looked kind of washed out, while the originals looked like they were supposed to. Just in Photoshop it's self did they look too saturated.

Any ideas with what this one could be???
