Description
When placing scrollview inside a flexlayout, I am facing the following exception in this latest release.

Note: This crash occurs from the latest release of MAUI 6.0.486

Version with bug
6.0.486 (current)
Last version that worked well
6.0.424

Did you find any workaround?
This is not a workaround, but setting HeightRequest and WidthRequest to the flex layout does not cause the crash.

I have the same problem but an app with a FlexLayout crashes with the same exception even without a ScrollView. I have created a simple repro project for it:

The crashes are on Windows only. It does not crash on Android, but the FlexLayout is rendered incorrectly there.

Digging into this, it appears that "Element not found" is a red herring; the underlying problem is a layout cycle.

I have this issue too.
Maui needs a dynamic and reliable flex solution. That dynamically wraps the controls based on container size.
In UWP/WinUI3 there is GridView. In HTML/CSS there is Flex display.
