First, this seems to be just some (kind of) symbolic link:
lrwxrwxrwx 1 root root 0 Jan 3 17:49 /proc/32039/exe -> /usr/bin/screen (deleted)
And I can't really execute it, neither as the user owning the screen

~ # /proc/32039/exe -ls
zsh: permission denied: /proc/32039/exe
Not sure if that's because of this fake symlink or due to other
