partial [ObservableProperty] with private setter triggers exception

[sn4k3]

My code:

[ObservableProperty]
[JsonIgnore]
public partial DateTime? LastSucceedDateTime { get; private set; }

MVVM generation:

[global::System.CodeDom.Compiler.GeneratedCode("CommunityToolkit.Mvvm.SourceGenerators.ObservablePropertyGenerator", "8.4.0.0")]
[global::System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage]
public partial global::System.DateTime? LastSucceedDateTime
{
    get => field;
    private set
    {
        if (!global::System.Collections.Generic.EqualityComparer<global::System.DateTime?>.Default.Equals(field, value))
        {
            OnLastSucceedDateTimeChanging(value);
            OnLastSucceedDateTimeChanging(default, value);
            field = value;
            OnLastSucceedDateTimeChanged(value);
            OnLastSucceedDateTimeChanged(default, value);
            OnPropertyChanged(global::CommunityToolkit.Mvvm.ComponentModel.__Internals.__KnownINotifyPropertyChangedArgs.LastSucceedDateTime);
        }
    }
}

Ofender line: OnPropertyChanged(global::CommunityToolkit.Mvvm.ComponentModel.__Internals.__KnownINotifyPropertyChangedArgs.LastSucceedDateTime);

Exception:

System.MethodAccessException: Attempt by method 'CompiledAvaloniaXaml.XamlIlHelpers.NetSonar.Avalonia.Network.BasePingableCollectionObject`1,NetSonar.Avalonia.LastSucceedDateTime!Setter(System.Object, System.Object)' to access method 'NetSonar.Avalonia.Network.BasePingableCollectionObject`1<System.__Canon>.set_LastSucceedDateTime(System.Nullable`1<System.DateTime>)' failed.

Somehow it want to access the setter and trigger the error. If I set to internal set this no longer happens.
The exception does not crash the app, but if you debug with rider it will keep showing this.
I have those properties binded at a DataGrid in readonly mode.

Any ideia why?

I have those properties binded at a DataGrid in readonly mode.

DataGrid columns are TwoWay bindings by default.
You need to specify Mode=OneWay.

Thanks, it works... However, it's a bit boring to define each field as OneWay when having such cases (Easy to forget).
By default DataGrid even if allow edit, if a member does not have a proper setter it won't enter edit mode.
Is this exception triggered manually by avalonia or by dotnet? If dotnet, wouldn't be safer to check if setter is within scope before trying to access it?

I tested a TextBox which is TwoWay, with a private setter and when trying to edit it will raise the exception. However if the binding is declared without a setter, eg: public string Text { get } = "Something"; No exception is triggered when trying to edit the TextBox.
For more sane and "error-free" I think the setter should be checked before invoking.
