…eption When ConcurrentMethodRunnerQueue.Dispose is called from a different thread it appears that the CancellationTokenSource is cancelled (via Dispose) inbetween creation of the Task and calling Task.Start(TaskScheduler). Switch from using Task constructor and Task.Start to the preferred Task.Run method. Added additional unit tests. Issue #3639

Hey
We see a crash from our end-users.
Wasn't able to reproduce this locally yet so no information other than the stack trace
CefSharp version - 90.6.50
System.InvalidOperationException: Start may not be called on a task that has completed.\r\n at System.Threading.Tasks.Task.Start(TaskScheduler scheduler)\r\n at CefSharp.Internals.ConcurrentMethodRunnerQueue.Enqueue(MethodInvocation methodInvocation)\r\n at CefSharp.Internals.ClientAdapter.OnProcessMessageReceived(ClientAdapter* , scoped_refptr* browser, scoped_refptr* frame, cef_process_id_t source_process, scoped_refptr* message)
