This is going to be difficult to find and fix.

As a current workaround, add the following code after copying the panels:

nazwa_2->setPosition({ "w > &.w ? 0 : (&.w - w) / 2" }, { "h > &.h ? 0 : (&.h - h) / 2" });
nazwa_3->setPosition({ "w > &.w ? 0 : (&.w - w) / 2" }, { "h > &.h ? 0 : (&.h - h) / 2" });

The w and &.w are still bound on the original widget, not to the copy, with your original. It is much more visible if written like this:

nazwa_1->setPosition(bindWidth(nazwa_1) > bindWidth(nazwa_1->getParent()) ...});

I'm going to see if I can make it bind to the new widget when strings are being used but I can't guarantee that that will be possible. But I can at least fix the crash since even if still bound to the old widget it shouldn't crash.

When the layouts are created from a string like in your code they should now be copied and re-evaluated correctly.
