Pressing left controll while holding w and s or w and d can only let you go in that one direction e.g pressing w and a tan pressing d but it will not move only going in the dirction of the a key

We weren't able to reproduce this problem from the description you provided. If GoldenHelmet is correct about what you meant, we can't reproduce that, either. It might be a hardware limitation as GoldenHelmet said, or it might be something unusual about your device, but in either case the developers can't find a bug if they can't see it.
If you are pressing a and d at the same time the left and right motions should cancel each other out.
If what you mean is that you can’t switch from a to d while holding ctrl + w, then you’re experiencing a hardware limitation of your keyboard, not a bug in the game. You may need to release some or all keys for it to register new presses.
