UE4.17 crashes when use widget undo

Hello,

I have a problem with widget which is placed in another widget. It seems that it is using the same CDO and makes Unreal Engine crashes every time when:

1.default properties are changed
2.compile
3.use undo
4.compile

The same behavior I get when UWidget is extended, 4example UButton as child blueprint. It’s even more annoying because changing defaults it’s the only way to change look of UWidget. So it is impossible right now to use undo because it crashes every time.

For easier reproducing I attach the video:
