### Minimal reproduction project

Example from  #68475.
if (scr.is_valid()) {
				r_type = _type_from_variant(scr);
				r_type.type.is_meta_type = true;
				return true;
			}
		}
		return false;
	}
	
	if (GDScriptLanguage::get_singleton()->get_named_globals_map().has(p_identifier)) {
		r_type = _type_from_variant(GDScriptLanguage::get_singleton()->get_named_globals_map()[p_identifier]);
		return true;
	}
	
	if (ClassDB::class_exists(p_identifier) && ClassDB::is_class_exposed(p_identifier)) {
		r_type.type.type_source = GDScriptParser::DataType::ANNOTATED_EXPLICIT;
		r_type.type.kind = GDScriptParser::DataType::NATIVE;

		} else {
			r_type.type.is_meta_type = true;
			r_type.value = Variant();
		}
	}
	return false;
