Select Object doesn't select all of the object

Hi,

I have a problem with the most recent version of Photoshop.

Whenever I use the "select object" function, the selection that Photoshop is doing doesn't select everything, it always leaves a gap of a few pixels at the edges of the canvas. Weirdly, this only happens on the right hand and at the lower edge of the canvas.

No other side of the canvas has ever been affected by this bug.

I realized it a few days ago when I was taking biometric passport pictures. The subject is almost filling the frame, and the subject touches the edges of the canvas on the left, right, and bottom edges. When using "select object", the behavior described above occurred. (See attached picture.)

The only way to fix it is to manually add the missing parts to the selection. Which, at least in this case, only takes a few seconds but kind of defies the purpose of having an automatic selection tool.

I tried different pictures, different people, different shirts, and even other cameras and file formats. It always comes down to the same problem.

At this point, I am pretty sure that it is a bug with the "Select Object" tool.

Any help with this matter is highly appreciated.

Kind regards
