Error to invoke workflow

My project crashes when It tries to invoke a work flow, I already checked and all the packages are installed I have looked for a solutions but I havent found it.

I hope someone can help to solve this issue because it is urgently

Orchestrator is not configured in my machine

error invoke

@aksh1yadav any ideas?

Could try importing uipath.core.activities manually in the namespaces section?

Googling the error suggests a problem with the namespace or xaml fileā€¦
