ESP32 Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled.

Hello,

When I use the sample code for ESP32, I get the following error:

I (342) main_task: Calling app_main()
FlashDB ESP32 SPI Flash Demo
[I/FAL] Flash Abstraction Layer (V0.5.99) initialize success.

When I examined the code, I noticed that the program crashed in this function in the fal_flash_esp32_port.c file. When I comment out the esp_partition_read function, the code does not crash, but it works incorrectly.

static int read(long offset, uint8_t *buf, size_t size)
{
esp_err_t ret;
LOCK();
//ret=0;
ret = esp_partition_read(partition, offset, buf, size);
UNLOCK();
return ret;
}
