Environment Details


Very rarely Designer can crash with a big red X across a window. One such situation has been observed and resolved.

Cause


.NET Framework corruption



Resolution


Repair or replace .NET Framework


If this is not a solution for your situation, you might try completely uninstalling and reinstalling the software.  Rather than manually deleting directories, you can rename them, so that it's easier to restore your settings later.  Similarly, backing up the registry by exporting it before you make changes is prudent.  Please open a case with Support.

I just noticed that (at least on my computer) the links don't open automatically.  I intend to fix this and republish the article, but in the meantime, please just open in a new tab.  Thanks

I am on version 2021.1 x64.

When this happened, it is always I have to force to shut down Alteryx via Task Manager.

It wont let me open or close the tab itself.

I encountered this issue today and I was able to solve it by :

 

- I just saved workflow with big red X

- Then just opened it again 

and it was gone.

I closed the workflow without saving my latest updates and it reopened without the error. Ü
