Python commandlet crashes when spawning actors in a level

Using the python commandlet to spawn actors within a Map and then saving it causes a crash in the commandline.

Tested in 4.21.2 (CL - 4753647), 4.22.1 (CL - 6063286),  4.23 (CL - 6338849)

1. Create a Blank project
2. Enable the Python and EditorScriptingUtilities plugins
3. Create a Blueprint Actor class called BP_Actor
4. Save the current map and name it NewMap
5. Create the following Python script:

import unreal

projectContentDir = "/Game/"
unreal.EditorLevelLibrary.load_level(projectContentDir + "NewMap")
test_bp = unreal.EditorAssetLibrary.load_blueprint_class(projectContentDir + "BP_Actor")
vector = unreal.Vector(0, 0, 0)
unreal.EditorLevelLibrary.spawn_actor_from_class(test_bp, vector)
unreal.EditorLevelLibrary.save_all_dirty_levels()

1. Open the Windows PowerShell to the location of the Engine/Binaries/Win64 for the current engine version you are testing in
2. Run the following command:

.\UE4Editor-Cmd.exe "<path to UProject file>" -run-pythonscript -script= "<path to Python script>"

Expected: The Project loads and executes the above python script
