Why does the "remove background" or "select subject" tool not correctly work on the newer versions?

I use mac and the recent photoshop versions 2023/24 has not worked correctly with "remove background" or "select subject". has anyone ever ran into this problem and found the solution to this? it works well with previous versions of photoshop but for some reason these newer versions it just comes out terrible for mac. i know it isn't my computer because ive tried it on multiple computers that are all mac.. any answers?

ive uploaded a picture of how it looks before and after using remove background option on mac.
