I encountered a similar problem and came here by doing an internet search.

for my case, I did my project on my pc, and to deploy it on another vm, which only has uirobot tray, and the uirobot tray doesnt automatically update your activities.

This error occured to me when my own machine’s uipath studio package manager auto update is turned on, and update one of my package, causing a version mismatch of its activities between my machine and the vm.

go to C:\Users<username>\AppData\Local\UiPath\Activities on both machines to verify the contents of both folder are the same.

If it isnt, just copy all the contents from your machine to the other machine.

Hello Sir,

I am facing the same issue since yesterday as cannot set an unknown member/‘UiPath.Core.Activities.GenerateDataTable.CSVParsing’.

I have looked at your post compared the activities of both my local machine and VM, i was missing Core activities content and as you said I copied all the content from local to production.

After doing all these it is still giving me the same error.

Please help me on Sir as my bot is failing on the production.

Appreciate your help.

Regards,
Raviteja.

i would suggest reinstalling the production environment - studio and robot
just copying core activities will not be enough as i m almost sure they are different
