Analysis
The crash occurs in egui's widget rect tracking when a widget changes its layer_id mid-frame. This appears to be triggered during navigation transitions in egui_nav when rendering
foreground/background layers. The issue is in the interaction between render_fg and render_bg in egui_nav, where a UI element is being created in one layer context but finalized in
another.
