The point is i suspect somewhere between Node 18.19.0 and Latest nodejs release, something has changed. I cannot ascertain that from the Major number only.

Please provide FULL Node Version numbers.

Thank you. This looks promising.

Certainly looking like something has changed in most recent LTS of V18 and V20.

Would be good to know if anyone is running the version IMMEDIATELY before current LTS versions `18.20.2` and `20.12.2`.

Is anyone running node-red on `18.20.1` or `20.12.1`?

The latest versions of Node 18/20 include a security fix that has broken Node-RED on Windows.

We'll have a fix for Node-RED later today.
