Unhandled Exception Error 2019.3


Hi everyone,


Not quite sure why I got this error but it will not go away regardless of my workflow I have open.  I think it happened after I accidentally imported an older charting tool within a premade workflow I was working with, however I have deleted that and am still getting the error.


Is there some way I can fix this on my own?




When do you see the exception? When you click on the file menu?

Hi I see this exact error when I click on the File u know how to resolve that?


Try wiping the registry entries in HKEY_CURRENT_USER\Software\SRC\Alteryx\10.0\MRU (using regedit)


I would recommend exporting to back it up first, but this may fix your issue. If not, I have one other thing you can try.
