C++ Help me with crash server tfs 1.2

I'm trying to set a 10 sqm limit of player (target) for the monster not to walk outside this limit when using the getRandomStep function

one way i managed to make it work is this way

bool Monster::canWalkTo(Position pos, Direction direction) const
{
    const Position targetPos = followCreature->getPosition();

    pos = getNextPosition(direction, pos);
    if (Position::getDistanceX(pos, targetPos) > 10 || Position::getDistanceY(pos, targetPos) > 10) {
        return false;
    }

    if (isInSpawnRange(pos)) {
        if (getWalkCache(pos) == 0) {
            return false;
        }
        Tile* tile = g_game.map.getTile(pos);
        if (tile && tile->getTopVisibleCreature(this) == nullptr && tile->queryAdd(0, *this, 1, FLAG_PATHFINDING) == RETURNVALUE_NOERROR) {
            return true;
        }
    }
    return false;
}

I added this inside the canWalkTo function

  const Position targetPos = followCreature->getPosition();
    if (Position::getDistanceX(pos, targetPos) > 10 || Position::getDistanceY(pos, targetPos) > 10) {
        return false;
    }

well everything works as I exactly wanted, but I found a problem, the server is crashing when a monster is attacking the player and he enters the protection zone...

i tried change the

 const Position targetPos = followCreature->getPosition();

To

 const Position targetPos = attackedCreature->getPosition();

but the problem (crash server) still persists, can someone help me how can i solve this?
