CorelDraw 2019 shutting down

Using CorelDraw 2019.  When I am working I get the message CorelDraw 2019 has stopped working.  A problem  caused the program to stop working correctly.   Windows will close the program and notify you if a solution is available.   Then I loose all the work that has been done since I last saved.   This happens 4 to 5 times a day.   Anybody have an answer for this problem?    Don M
