...I forgot to add the layer name to the options...

filepath = "[complete file path and file name and extension (.gpkg)]
lyrname = "test_layer"
fields=QgsFields()
fields.append(QgsField("test_field", QVariant.Double))
opts = QgsVectorFileWriter.SaveVectorOptions()
opts.layerName = lyrname
writer = QgsVectorFileWriter.create(filepath, fields, QgsWkbTypes.Point, 
QgsCoordinateReferenceSystem("EPSG:4326"), 
QgsCoordinateTransformContext(), opts)
del writer
