for tests, classes can be disabled entirely in file BasicData.gd inside disabled_classes variable

I don't have build with sanitizers, but probably more errors could be found with its help

That's pretty neat!

That first crash actually looks to be a bug in Godot itself, where ClassDB::can_instantiate only checks against API_EDITOR and not API_EDITOR_EXTENSION. I'll see about making a PR to fix that.

That second one is definitely my fault though.
