Unhandled Exception Error 2019.3

[avavalley]

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?

Thanks

I did try deleting that one along the 4/10 MRU's, restarted the machine, no luck.

In File Explorer, browse to %LOCALAPPDATA\Alteryx and delete everything in the Connections folder.

[contextworld]

The Connections folder was already empty.

Okay. In File Explorer, browse to %PROGRAMDATA%\Alteryx\ErrorLogs\AlteryxGUI and look for .log file with the latest modification date. Open it and tell me the contents of that file.

In the registry, delete 'ApplicationCloseDate' inside of HKEY_CURRENT_USER\Software\SRC\Alteryx\4.0

[contextworld]

I have previously tried deleting the whole 4.0 and 10.0 with all their sub-directories, so this was already attempted.

[jpoz]

Go into HKEY_CURRENT_USER\Software\SRC\Alteryx\4.0 and ADD 'ApplicationCloseDate' with a value of '03/02/2020 10:00:00'

[contextworld]

Deleted it and added it again. Gives that error, if I click OK I can continue working in Alteryx. Closed alteryx, changed the updated value manually to 03/02/2020 10:00:00, still same error when starting Alteryx.

Log again:

There was an issue fixed for 2020.1 that involves computers using a date format that isn't the standard english format (MM/DD/YYYY HH:MM:SS). I think that is what you are encountering.
