Esp32-(xQueueGenericReceive)- assert failed

Hey guys i have been working on a project in which the analog values sampled at a particular frequency and stored in array. Then the value will be sent to user application ESP32 BLE. But I got stuck in this error.

/home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/freertos/queue.c:1443 (xQueueGenericReceive)- assert failed! abort() was called at PC 0x4008e1d5 on core 1

Backtrace: 0x40091b38:0x3ffe0b20 0x40091d69:0x3ffe0b40 0x4008e1d5:0x3ffe0b60 0x400d1a2d:0x3ffe0ba0 0x4008e525:0x3ffe0be0

I am Using Esp32arduino and Free Rtos for programming i error is in the semaphore from the interrupt but i couldn't able to find out exact solution. Please help me out guys

@khottabhutta Why do users choose to ignore the advice on posting code ?

The easier you make it to read and copy your code the more likely it is that you will get help

Please follow the advice given in the link below when posting code , use code tags and post the code here

Your post was MOVED to its current location as it is more suitable.

edit the OP and put the code in code tags.

Decode the exception error using the ESP Exception Decoder.
