nRF52 fall project when MITM = 1.

SDK13, S132

Project stopped after start. I use standart initialization:

static void peer_manager_init(void)
{
ble_gap_sec_params_t sec_param;
ret_code_t err_code;

err_code = pm_init();
APP_ERROR_CHECK(err_code);

memset(&sec_param, 0, sizeof(ble_gap_sec_params_t));

sec_param.bond              = SEC_PARAM_BOND;
sec_param.mitm              = SEC_PARAM_MITM;
sec_param.lesc              = SEC_PARAM_LESC;
sec_param.io_caps           = SEC_PARAM_IO_CAPABILITIES;
sec_param.oob               = SEC_PARAM_OOB;
sec_param.min_key_size      = SEC_PARAM_MIN_KEY_SIZE;
sec_param.max_key_size      = SEC_PARAM_MAX_KEY_SIZE;
sec_param.kdist_own.enc     = 1;
sec_param.kdist_own.id      = 1;
sec_param.kdist_peer.enc    = 1;
sec_param.kdist_peer.id     = 1;

err_code = pm_sec_params_set(&sec_param);
APP_ERROR_CHECK(err_code);

err_code = pm_register(pm_evt_handler);
APP_ERROR_CHECK(err_code);

}
