"the type initializer for Delegates threw an exception" - using Create Runtime

[vruetten]

Hi all
I'm a newbie to Bonsai and am trying to get the "Create Runtime" node working.

I've tried following the documentation: https://bonsai-rx.org/python-scripting/?tabs=windows
but still run into an error.

I've installed python (v3.12.8). I created an environment as instructed via python -m venv .venv, activated it and tested that I could indeed launch python from the command line using this environment.
I then point the runtime node to this folder (with or without an empty script in the "ScriptPath") with or without the python environment activated and get the "Delegate" error.

Any ideas what I might be doing wrong?
Thanks in advance for any help.

I'm running

• Windows 11 Pro
• Bonsai 2.8.5
• Python 3.12.8

Prior to this I attempted installing python via miniforge (and tried various versions of python) but couldn't get past this error.
