Something wrong in part 6 (Mutex demo)

[m3y54m]

Hello,
First of all, thank you for this great course.
I'm currently following the course and trying to write and test all the demos and challenges.

In part 6 where you talk about Mutex, I noticed that there is something wrong and only one of the tasks is executed, and the other task is completely blocked and never executed.

I found out this problem by adding these lines before Serial.println(shared_var); line in esp32-freertos-06-demo-mutex.ino.

The function pcTaskGetName(NULL) returns the pcName of the task.

      Serial.print(pcTaskGetName(NULL));
      Serial.print(" : ");
      Serial.println(shared_var);

This is the resulting output:

I still don't know why only one task is running. Maybe it has something to do with ‍‍xBlockTime or something else.
