Could it be because UiPath.Core.Activities is out of date?

@DEATHFISH Ohh I think it is. Because I couldn’t find it in mine. Also I guess it is Split it into two Packages now , System.Activities and UiAutomation as the below post suggests :

Core activity not found in Manage Packages although UiPath.Core.Activities.2018.3.6848.19350 file is in the packages folder of UiPath

[image] core activities now are split into two new packages on the excel workflow, i suspect you have an older version of excel package installed, try upgrading to latest release - 2.3.xyz

Also Try updating the System.Activities and UiAutomation Packages to the Latest version and Check
