Frameworks Version: 5.64.0
Operating System: Linux 5.3.7-301.fc31.x86_64 x86_64
Distribution: Fedora 31 (Workstation Edition)

-- Information about the crash:
- What I was doing when the application crashed:
I had just finished decorating the global feel I wanted but then the system would close out when I was trying to choose my font or work my way to choosing a different background.

The crash can be reproduced every time.
