Where do you start when you see "An Unhandled Exception occurred"? There could be a wide range of causes for this kind of error, so the resolution requires that you collect some more information.
An Unhandled Exception occurred.

Click OK to send the development team the error log so that we can fix this error in a subsequent release.
Story of my recent life working with Alteryx is continuously receiving the message: "Object reference not set to an instance of an object." before Designer becomes utterly unusable. Please fix this!!
Actually i have this message in the
C:\ProgramData\Alteryx\ErrorLogs\AlteryxGUI
Message: Invalid URI: The format of the URI could not be determined.
what is the solution for this error?
@SaadNaser
I would conclude that somewhere there is a URL that is not a valid format. The full error message might tell you where.
Possible places I can think of would be in the connected galleries or in a phone home configuration. If you cannot find more detail from the full message, then start by looking at the %AppData%\Alteryx\Engine\UserSettings.xml and the C:\ProgramData\Alteryx\RuntimeSettings.xml to see whether you can find any URLs that either have typos in the http:// or https:// or don't end with a .TLD. Please note that the RuntimeSettings.xml is almost always on the C: drive, even if the Designer (or Server) was installed to a different location. Also, ProgramData is a hidden directory, so you might need to paste or type in the path.
As always, users who have paid licenses can open a case with Support. It will be most efficient if you include
If things had been working correctly in the past, please mention that along with anything you know has recently changed in your computing environment. The Customer Support Engineer (CSE) will need that information to determine what the root cause is and to help you correct it.
I want to add to my previous reply, that i have reached out to support. I am just referring to the fact that a Complete Uninstall of Alteryx Designer is not a silver bullet.
