"Freeze Viewport” behavior of nDisplay in UE5.5

Hello,
In this post, it was mentioned how to enable “Freeze Viewport” to stop drawing the outer freustum and draw only the inner freustum.

I tried this with a UE5.3 project and it worked as reported.

However, when I tested it with UE5.5.4, all views are not displayed when this flag is enabled.

Is it possible to reproduce this situation in UE5.5 or later, where only the outer freustum is no longer rendered, but the inner freustum is still rendered?

I would like to know if there is any information on how this can be improved in later versions or if other flags should be used.

I would appreciate an answer as soon as possible.
Thank you in advance.
