Hello guys,
I am taking advantage of the time at home to play with my ESP32. But I ran into a problem.
I am making a program with WiFi events and interrupt with timer. The programs individually work well but when joining them the program shows the following error and restarts all the time.

and my test program is as follows

}
is there any way to fix it?
