Bookmarks not working after script with CIM objects

CordulaGöke

I have a script to adjust the scale bar and grid as CIM objects. After I ran this script, the manual use of bookmarks is not working anymore. I cannot set bookmarks nor zoom to existing bookmarks.  Do I need to release the CIM objects, update or something else? When I close and reopen the map, everything is fine. I need to go manually through all bookmarks before export.

@BrennanSmith1  good point .  First I thought it had solved itself, but after I zoomed and ran the rescaling of scalebar and grid several times, zoom to bookmarks stopped working. Yes I use aprx = arcpy.mp.ArcGISProject("CURRENT") in a jupyter notebook. It is the first project where I zoom manually through bookmarks and I also added the update_grid() only recently.

import arcpy
import os
import pandas as pd

aprx = arcpy.mp.ArcGISProject("CURRENT")

arcpy.env.workspace = os.path.dirname(aprx.filePath)
arcpy.env.addOutputsToMap = False

    for elm in lyt_cim.elements:
        if elm.name == "Scale Bar":
            elm.unitLabel = "km"
            elm.labelFrequency = "Divisions"
            elm.division = round(mf_camera_scale / 80000, 0)
            elm.divisions = 2
            elm.subdivisions = 2

    # Apply the updated CIM definition back to the layout
    lyt.setDefinition(lyt_cim)
