The solution is to add -w as a launch argument to the end of the environment variable value. This waits for the process to close which houdini requires according to support, and keeps the item loaded in a single thread.

EDITOR = "C:/Users/XXXX/AppData/Local/Programs/Microsoft VS Code/Code.exe -w"

I had the same question and support suggested:

houdini -foreground script.py

And if your test needs to query or manipulate the Houdini UI, then:
houdini -foreground waitforui script.py

Also, we normally set these environment variables beforehand for testing purposes:
- HOUDINI_DISABLE_CONSOLE=1
- HOUDINI_NO_SPLASH=1
- HOUDINI_DISABLE_BACKGROUND_HELP_INDEXING=1

Python. Interestingly it works fine on my workstation, I just can't identify the cause for why it occurs in some other systems.
