Error Unhandled exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

With the version AasxServerBlazor.v0.3.1.132-aasV3-alpha-latest, when I use the option "--opc-client-rate 500", I get the following error: Unhandled exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object.) ---> System.NullReferenceException: Object reference not set to an instance of an object. at AasxServer.Program.ReadOPCClient(Boolean initial) in D:\a\server\server\src\AasxServerStandardBib\Program.cs 2291 at AasxServer.Program.Run(CommandLineArguments a) in D:\a\server\server\src\AasxServerStandardBib\Program.cs 987 --- End of inner exception stack trace --- at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) at System.Threading.Tasks.Task.Wait() at AasxServer.Program.<>c.
