Masking doesnt detect subject and put red rectangle around it instead

Im trying to edit my photos but somehow the masking isnt dectect the subject the right way at all.

When doing the subject masking, it's either not detect or detect somewhere not the subject. I also tried with Brush and Object masking as well, and none working.

=> None of the masking option for me working properly, even after uninstall and reinstall the program

Please send help, thank you!
