Bug on subject selection and remove background v.27.0

Hello,

I started using the new photoshop version 27.0 and noticed some really annoying problems while using the "subject select (SS)" and "remove background(RB)" features from the taskbar, in some instances it just doesn't recognize images at all, images that it had no problem working on the previous version.

At first I thought this was a problem after i rasterized the image, as soon as I imported and used SS or RB on the smart object it worked as expected. But if i rasterized the same image and then tried to use the same features, photoshop would select the outer bounds of the image imported.

But after trying again on both smart objects and rasterized images i realized that the same thing happened with both types of layers.
I also thought this might have been a problem with images generated with firefly, but again, i had the same problem with photos and other files that were not ai generated. 
Here is an example of the weird selection it made on non-generated image as a smart object layer, i used both SS and RB and then created a mask. Also an example of a image that it only selected the outer bounds when using SS and RB.

After working on the same project in different PS versions this was very weird since it wasn't happening on the previous versions only in v27
