[Bug] [macOS] Rendering Line shape crashes the app in case xCode 13.2 installed

[sady4850]

Description

With Xcode 13.2 installed, any Xamarin Forms app that uses Line shapes crashes immediately when the line is rendered.

Steps to Reproduce

1. Make sure xCode 13.2 is installed
2. Add a Line shape in XAML (or in code)
3. Run app
   For example, this page will crash the app:

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="XFLineBug.MainPage">

    <Grid>
        <Line X1="10" Y1="10" X2="100" Y2="50" Stroke="Red" StrokeThickness="3"/>
    </Grid>

</ContentPage>

Exception thrown: Could not initialize an instance of the type 'CoreGraphics.CGPath': handle is null.

Repro project: CGPathIssue.zip
(this is a clean new Xamarin Forms macOS project with the MainPage changed to show a line shape)

Expected Behavior

Line is shown on screen

Actual Behavior

App crashes immediately.

Fixed with #14993

@jfversluis How can this be fixed by PR #14993? This issue is for MacOS but the PR only changes the iOS code

[jfversluis]

If you look in the csproj file of the macOS project you will see that the ShapeRenderer is linked and thus shared from the iOS codebase

@jfversluis Right, just figured that out as well.
Thanks, learned something new today :-)

[jfversluis]

Depending on which area iOS and macOS code is pretty similar so sometimes code is shared between them. But I can see that this is something you would need to know, else it isn't very obvious :)

Should be any day :) probably early next week

I have this same bug using "<Path", @pictos recommended me to use version "5.0.0.2336-nighly", which already has the fix and everything is fine so far. Please, what is the release forecast for a new version in release?
