ArcGIS Project (.aprx) lock not released

[nita14]

Dear All,

It seems that arcpy.mp does not release the lock of the resulting (new) aprx document. The following code does create a new aprx file:

aprx_project.saveACopy(os.path.join(workspace, prefix, name_to_save))
del aprx_project

Unfortunately, the lock persists on the new .aprx file. Is there any way to remove it? Only after I close the ArcGIS Pro which I use to run the script, the lock is released.

Any hints are much appreciated!

I am having this same issue using arcpy.mp.ArcGISProject and the pro project gets locked into Read-Only mode. 

prj = arcpy.mp.ArcGISProject(prjPath)

del prj

del prj doesn't work to unlock the project. Any suggestions on how to get the script to unlock the project?
