I have a old studio version which was like this:

But later, when I updated UiPath Studio and use the compatibility mode.
It updated the activities but now is showing this error. I don’t know what exactly it means and how to solve it
The line is:
path.Combine(convert.ToString(in_Config(“LogFilePath”)),string.Format(in_Config(“LogFileName”).ToString,DateTime.Now.ToString(“dd_MMM_yyyy hh_mm”)))
