@prospero78 Could you please share the output of the race condition dump (it should normally print a stack trace of the error)?

Unfortunately, but the dump was not preserved. I just launched a data exchange cycle with a web browser in a separate thread. And then the show began.

I solved this problem by allocating the main thread of execution in a separate thread. And all the signals arrive on different channels in a separate stream. Although it is worth recognizing: the situation is sad, and the author abandoned his project a bit.
