The masking tools are not working properly anymore after update to 12.4.

After I updated to 12.4, the masking tools are not finding the subject or background properly anymore.

I have a bunch of colleagues at work for me, and everybody's computer seems to be a little bit different.

When we first started using these tools. Everything seems to work flawlessly. Group shots of everyone were chosen on the subjects. Backgrounds behind subjects were always chosen properly through AI. But since I've updated the software to 12.4. It no longer is seeing the subject we're background properly.

I sent a screenshot to my colleague. He has the same exact shot that I have. And when we went to select the subject, it selected parts of the subjects and parts of the background. I've been having this program problem on every photo. It is not finding the edges of people or backgrounds. And not distinguishing between, the two in many cases. This is a new issue.. Again, my colleague has 12.4 as well and his is doing a much better job distinguishing between subject and background. In some cases I have to select each subject in the group. Select all of them and invert. That will give me a properly cut background in many cases. But it is not perfect. It doesn't always work just right. In some cases in a group shot some people cannot be found by the AI all of a sudden this new upgraded version. I tried uninstalling and reinstalling. But the problem still exist. I'm wondering if it's compatibility with my computer.
