pyRevit Loader - Error Loading pyRevit

Hello, any idea why I am getting this error when opening Revit?
Revit loads ok after I click “CLOSE” but pyRevit is not loading.

Thank you in advance!

Second half of the error screen:

I uninstalled pyRevit and reinstalled it again and the issue was resolved!

I tracked down the reason, it was a typo in the bundle file.
