Why photoshop change the color of my PNG when I import them into the program?

As Per says. This is an untagged image, and the two applications have different default working color spaces. From the looks of it, sRGB in Photos, and Adobe RGB in Photoshop. If it had an embedded profile, that profile would be correctly read in both applications - and they would be identical.

You have a PNG open in the Windows Photos app (which is color managed BTW), and a Tiff open in Photoshop, so it's not the same image.

Also, the # at the end of Tiffs file name indicates that it is untagged – it does not have an embedded profile.

Never work with untagged material, it disables color management, and you'll end up with problems like this.

When saving files in Photoshop, always check ICC profile.

I'm assuming that you are comparing a non-colour managed program to Photoshop, which is colour managed.
