Hi @urupeange , thanks for reporting. The issue is due to the fact that the default output vector layer extension has been incorrectly set to the "xtf" extension ("Interlis 2" format).

In order to avoid the issue, you need to set the Default output vector layer extension (in Settings->Options->Processing->General) to a value other than "xtf" e.g. to the value "gpkg" ("GeoPackage" format) which is the default for such option.
