Python: Python activities do not work with virtual environments

[andumorie]

Describe the bug Trying to set the Python path to a virtual environment results in an exception when using the Load Script activity: "There was no endpoint listening at net.pipe://localhost/UiPath.Service/Host_IPythonService_13976 that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ----> System.IO.PipeException: The pipe endpoint 'net.pipe://localhost/UiPath.Service/Host_IPythonService_13976' could not be found on your local machine."

To Reproduce Steps to reproduce the behavior:

1. Add a Python Scope activity
2. Set the path to a virtual environment
3. Use the Load Script activity
4. See error

Expected behavior Should work just like when providing the system Python path

I would also be very interested in a solution. Is it nowadays possible to use venv in UiPath?
