Themes no longer working for WINDOWS 10 (opens in new tab)

I am a Windows 10 user,I hope someone here can help me out:My Windows Themes suddenly stopped working. I can select all other categories under "Personalize", but clicking on "Themes" results in the application crashing (i.e., the window closing) and a SystemSettings.exe dump file being created.Upon booting into Safe Mode, I got a direct error message that I screenshot:How can I easily fix this without resorting to unwanted measures such as a system restore or having to create a brand new user...
