Cannot create unknown type '{}DirectoryExists'

While running one of the programs I came up with the following error.Please help me resolve the error.

Source: System.Xaml

Message: Cannot create unknown type ‘{}DirectoryExists’.

Exception Type: XamlObjectWriterException

I even checked for the packages and all of them were installed.

I believe it just says that you are missing ‘UiPath.FTP.Activities’. Did you checked if it exists? If it does then just do remove and try to install again.

I did the same but it still gives me the same error.

@ShubhamVerma Update all the packages

All the packages are updated and still the same error.
