Importing Visual Scripting Assets before opening visual scripting graphs throw errors.
When importing new visual scripting assets in a project where you never opened visual scripting, a bunch of errors start to log about.

Reproducible on:

• All VS versions
• Unity version: 2020+

{}Steps to Reproduce{}:

1. Create a new project in 2022 (Spline package only work from there)
2. Import the spline package from the zip file in the package manager
3. Import the spline sample from the package manager
4. Open the scene "Assets/Samples/Splines/1.0.0-pre.8/Spline Examples/Scenes/9 - Visual Scripting/Visual Scripting - Spline Evaluation.
5. In the Hierarchy, click on the Game Object AnimateAlongSpline. You should start to see error.
6. Press play
7. Now you should see other errors.

To make it work

Open a script graph, now unity will build the node library and no error will occur.

Expected results

Everything should work fine even if the user never opened a script graph in the project.
