Uninstalling Visual Studio 2017 "Unexpected character encountered while parsing value"

I'm attempting to uninstall Visual Studio Enterprise 2017 using the Visual Studio Installer on Windows 10 Professional but when I try to do so I hit this error:

[0d1c:002d][2020-02-12T16:28:26] Error 0x80131500: Unexpected character encountered while parsing value: <. Path ''.

Has anyone else run into this issue and know how to successfully uninstall this application?
