I have this code that does not work. I get this error:

assert failed: xQueueGenericSend queue.c:832 (pxQueue->pcHead != ((void *)0) || pxQueue->u.xSemaphore.xMutexHolder == ((void *)0) || pxQueue->u.xSemaphore.xMutexHolder == xTaskGetCurrentTaskHandle())

Can someone help me please?

To be honest, i have no idea. It crashed on queue, but i dont remember any queues in the library.
Is it really whole code? Try to update arduino/library version.
