Unable to assign subclass node in the editor when it inherits an abstract class.

[datouzhu125]

@RegisterClass
class Sample : Node2D() {
    @RegisterProperty @Export lateinit var node: Parent
}

@RegisterClass
abstract class Parent : Node2D() {
}

@RegisterClass
class Child : Parent() {
}

Modify Parent to a normal class, then you can assign.

@RegisterClass
open class Parent : Node2D() {
}

By the way, when I made the change, after building, the editor crashed,here's the error log. hs_err_pid23860.log
