Problem With Corel Photo Editor - Cut Out Crashing


I am totally new to Corel (and any image editing software), and I am trying to cut out the background on an image (just as a test on this occasion). I have followed instructions from a youtube video, and all goes well with the outlining , the filling however when I click okay I get an error message saying "Corel PHOTO-PAINT 2017 (64bit) has stopped working" "A problem caused the program to stop working correctly. Windows willclose the program and notify you if a solution is available". There is then two buttons I can press "DEBUG" or "Close Program".

How can I fix this?
