Update. Using the deprecated QgsVectorFileWriter.writeAsVectorFormat() instead of QgsVectorFileWriter.writeAsVectorFormatV2() solves the issue. So I suppose there is a bug somewhere in the new implementation.

The first run inside the loop goes well but it crashes at the second run when trying to write a GPKG with the error below: options.driverName = "GPKG" RuntimeError: wrapped C/C++ object of type SaveVectorOptions has been deleted I tried with a much shorter loop and it has no problem at all writing the GPKG at each cycle. I'll try with the now deprecated QgsVectorFileWriter.writeAsVectorFormat() to see if it makes any differences. Any idea why it could happen? By the way, I'm defining options = QgsVectorFileWriter.SaveVectorOptions() just before options.driverName = "GPKG" each time. Thanks Jean-François Bourdon, ing.f.
