Unhandled crash when modifying the chatbox timeline

[insomnyawolf]

How to replicate:

Open the timeline, leave it running for a while and randomly when trying to modify clip length or position (usually in a way that the current playing part of the timeline ends out of the clip) you may get this error.

Error is on:

//VRCOSC\VRCOSC.App\UI\Views\ChatBox\ChatBoxView.xaml.cs:402
private void TimelineContent_OnMouseMove(object sender, MouseEventArgs e)
{
    if (draggingClip is null) return;

    var layer = (int)Math.Floor(e.GetPosition(Timeline).Y / 50d);
    if (draggingClip.Layer.Value == layer) return;

    DragDrop.DoDragDrop(this, new object(), DragDropEffects.Move);
}

Notes:

Very hard to replicate, likely to be timing sensitive. Possible to be related to Windows11

Result:
