Try backing up and then removing everything inside the C:\Users{username}\AppData\Roaming\Alteryx\Engine folder except for the GalleryAlias.xml, UserAlias.xml, and UserConnections.xml files (so remove all the version folders). This will force Alteryx to generate a new user settings file.

*Note: this removes all user settings, favorite tools, window positions, default colors, proxy settings, etc.
