Problem solved: It seems that the shell received an invalid value in the DISPLAY environment variable (wayland-0) and passed it to qtcreator. Manually changing DISPLAY to ":0" fixed the problem so that qtcreator started correctly. Also, selecting qtcreator as a favorite and starting it by clicking on the icon in the dock worked fine.
