Looks like a regression after https://github.com/godotengine/godot/pull/76836, (it's happening on Windows after instalment by default). There should be a way to fix it, either by disable that error or providing a link where that certificate can be downloaded and installed.

### Steps to reproduce

Simply run any project or editor.

### Minimal reproduction project

No need, too easy to reproduce.
