Error: Cannot create unknown type '{http://schemas.uipath.com/workflow/activities}OpenApplication'

I run my process OK on DEV enviroment. When I deploy it to PROD through orchestrator and run it it throws this new error that does not happen in DEV.

Do you have any idea how to fix it. I do not have Studio on PROD ENV.

Please make sure that all packages are available in your PROD machine with same version.

How to do that?

Can you check under libraries if ‘Uipath.UiAutomation.Activities’ package is available?

Thanks

Yes, I can see it is installed on orchesrator libraries.
