ArgumentOutOfRangeException in ParseAsUTF8String

[oddbear]

Tested both from NuGet and cloned Repo (lastest master commit in picture).

I am not sure why this happens, as I cannot always reproduce it (will update if I figure out more).
When I change values on a valueChoices list in a dynamic action (inlined), some times this happens, and the choice is selected in TouchPortal, but the OnListChangeEventHandler is not called.

Message: Specified argument was out of the range of valid values. (Parameter 'start')

Tried changing random stuff until the problem went away.
By changing ProcessQueueingService UnboundedChannelOptions, the problem seemed to go away. More testing needed (this option might be the wrong fix).

var channel = Channel.CreateUnbounded<ReadOnlySequence<byte>>(new UnboundedChannelOptions()
      {
          SingleReader = true,
          AllowSynchronousContinuations = true
      });
