arcpy.mp.ArcGISProject('CURRENT') works but arcpy.mp.ArcGISProject(project_path) does not.

I have created a script to add images into a map. Both arcpy.mp.ArcGISProject('CURRENT') and  arcpy.mp.ArcGISProject(project_path) allow me to access the project and print the current layers but using the path does not allow me to add data in. Here is my script: 

tif_folder = r"C:\folder"

# Set aprx as your current project
aprx = arcpy.mp.ArcGISProject('CURRENT') 
#aprx = arcpy.mp.ArcGISProject('project_path')

# Get the map from the project using the index for a given map
map = aprx.listMaps()[0]  

#assign existing layers
existinglayernames = [l.name for l in map.listLayers()]
print(f'existinglayernames: {existinglayernames}')

#add files that are not in the project yet
for file in os.listdir(tif_folder):
    fName, fExt = os.path.splitext(file)
    if fExt != '.tif' or fName + fExt in existinglayernames:
        #  Skip this file and continue to the next one
        continue
    filepath = os.path.join(tif_folder, file)
    map.addDataFromPath(filepath)
    print(f'File name: {fName}')
    

Both options print the existing layers and the layers that are being added. but,  the path does not actually add the file.

Yes, or will create a copy, of the whole project. It shouldn't take up too much space, because it doesn't copy the tater data.

As I said, you can also use the aprx.save() method, but only if you don't have that project open.
