visual script is generally not stable (often crash)

[Jummit]

I just wanted to put this here, I am on Linux and whilst working with visualscript I never encountered any bugs or crashes.

[fire]

Tried on Windows and https://github.com/godotengine/godot/commit/ae6c390eb215c8c3f27f0f7a249cb2c07fcfc08a.

Still crashes.

[KoBeWi]

Seems like it still crashes, but the script is likely invalid/corrupted and it's not editor crash, so closing.

If someone can create a crashing script in Godot 3.2.3 or newer, please comment and we can reopen this.
