I'm using nRF52840 with nRF5_SDK_17.1.0_ddde560, and using the ble_app_multirole_lesc example file.
When I port FreeRTOS to the multi_role, there are no errors during compilation, and the counter runs after starting the debug session.
However, the RTT viewer shows <error> app: SOFTDEVICE: INVALID MEMORY ACCESS,
and the phone cannot connect to it.
Below is a portion of my code and files:

#include "FreeRTOS.h"
#include "task.h"
#include "timers.h"
#include "queue.h"
#include "portmacro.h"
#include "event_groups.h"
#define COUNTER 1

{
uint8_t event; // event type
void *pData; // event data pointer
}mrEvt_t;
int counter = 0;

TimerHandle_t xTimer_COUNTER;
void vAppTask(void *pvParameter);
static BaseType_t multirole_enqueueMsg(uint8_t event, uint8_t state, uint8_t *pData)
{
BaseType_t success;
mrEvt_t *pMsg = pvPortMalloc(sizeof(mrEvt_t));
if (pMsg)
{
pMsg->event = event;
pMsg->pData = pData;
success = xQueueSend(appQueue, &pMsg, portMAX_DELAY);
return (success == pdPASS) ? pdPASS : pdFAIL;
}
return pdFAIL;
}

{
multirole_enqueueMsg(COUNTER, 0, NULL);
}
void initTimer(void)
{

}

}

{

break;
}

}
}

}
