There was an error while loading: Object reference not set to an instance of an object.
When starting Alteryx Designer, the following error is received:
There was an error while loading: Object reference not set to an instance of an object.
- Alteryx Designer
- All versions
There are a few possibilities that could contribute to the error, mainly related to setting files are not reachable or corrupt state.
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.
If the above solution does not work, you can install a different version of Alteryx Designer, or upgrade your existing version to the latest one. This usually resolves the issue.
