Zusätzliche Informationen
After further investigation it was discovered that the layer being set from simple symbol to graduated colors did not have appropriate attributes to support this renderer. The same occurs in the UI and an error message appears stating the issue.Workaround
Add a layer file (template) that has the renderer set for the point FC, then change its data source to your correct point FC, update the classificationField to refresh the stats for the new layer and remove the original, replaced layer.
p = arcpy.mp.ArcGISProject('current')
m = p.listMaps('Map')[0]
lyr1 = m.listLayers('SimplePtLayer')[0]
lyrFile = arcpy.mp.LayerFile(r"C:\Temp\GraduatedColors_Point.lyrx")
lyr2 = m.addLayer(lyrFile)[0]
lyr2.updateConnectionProperties(lyr2.connectionProperties, lyr1.connectionProperties)
sym = lyr2.symbology
sym.renderer.classificationField = 'Elevation' #resets field and stats
#Update symbol template - keep in mind lyrx could already have it.
symTemp = sym.renderer.symbolTemplate
symTemp.applySymbolFromGallery('Square 1')
sym.renderer.updateSymbolTemplate(symTemp)
#apply changes
lyr2.symbology = sym
#remove original layer
m.removeLayer(lyr1)
