Import Argument of Invoke Workflow crashes by clicking on expansion icon Studio 21.10.4

Hello everyone, I would like some help to check a bug in the invoke workflow file activity within uipath studio.

In uipath studio version 21.10.4 when I call the invoke workflow file and after putting the value of the argument, the version shows me a symbol (Image number 1) that would expand the argument, but when I click on the symbol, I get an error.

Short error message:
Exception has been thrown by the target of an invocation.

Expanded error message:

Error: System.Exception: Exception has been thrown by the target of an invocation.
—> System.Exception: Target property is not an argument

Important note: The symbol is not shown when the argument field is empty. It appears only after adding a variable to receive the value.

May someone help me?

Thanks
