Select and Mask - Selection is invisible

Hi There,

I have a picture of a person, I want to remove the background.

I select "Select and Mask"

Now I select "Select Subject"

Prior, there was a visible selection around the person.

Now, no selection is visible anymore.

How do I get the selection back?

Even if I use "Qucik Selection Tool" there is no selection visible.

"Reset the Workspace" button did not solved the issue.

Thanks,

M.P.
