Customized Activity Error

Hi Team,

We are working on the Uipath Studio 2018.2.3, the issue is that we have added a newly created Customized Activity in a existing working flow with few other activities and as per the requirement needed to change the Activity and I have replaced the Activity with the updated activity in both Program Files and Studio, after the updation facing the error as “Activity Couldn’t be loaded because of error in xaml” .

The activity is available but the error is as mentioned. any suggestion will be helpful and thank you in advance.

Which activities do you used in the Customized Activity ?


Thats is a customized nuget File,which was made from C# code.

try to uninstall and install the package again with updated version.
