SFML RenderWindow taking a long time to open a window

I know this is essentially a duplicate, but this wasn't ever answered. I'd like to mention that I have followed the tutorial for using SFML along with Visual Studio, and I'm running a 64-bit project with 64-bit SFML. The window loaded instantly a few times, and now consistently takes 40 seconds to open on new builds/debugs. I also have the downloading of debug symbols off. My graphics drivers are up to date and my HDD is fine. This is the code:

 #include <SFML/Graphics.hpp>

int main()
{
sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");//This one
sf::CircleShape shape(100.f);
shape.setFillColor(sf::Color::Green);

while (window.isOpen())
{
    sf::Event event;
    while (window.pollEvent(event))
    {
        if (event.type == sf::Event::Closed)
            window.close();
    }

    window.clear();
    window.draw(shape);
    window.display();
}

return 0;
}

Everything runs at normal speed, except for RenderWindow, which again, takes exactly 40 seconds every time. Does anyone know how I could fix this? I've been having this issue for a few weeks now.

e: Could it be my CPU? It's not the best but I can still run most games just fine as I have a 1050ti. My current CPU is an i5-2500k, although I believe I got the same issue on an A10-5800k.

Solution

EDIT: Before you resort to the solution below, try updating your keyboards firmware! You're most likely using a Corsair keyboard, so download Corsair's iCue and update your keyboard drivers. This will most likely fix these issues. If it didn't work, then try the following:

Since OP didn't reply any further, I tried to find a workaround myself, as this issue still exists in 2020. This workaround requires you to compile the libraries yourself. So download the source code and change the following:

In WindowImpl.cpp, navigate to the function WindowImp::WindowImp and comment out the whole function body.
In WindowImpl.cpp, navigate to WindowImp::popEvent and comment out the call to processJoystickEvents

As long as you don't use the Joystick part of SFML this should work without issues.
