Processing video library isn't loading videos

Hello, I’m using Processing 4.0b7 (also tried with previous versions), and installed its Video Library. I have the following code (Im literally just trying to play a video):

    import processing.video.*;
    Movie video;
    
    void setup() {
      size(640, 480);
      video = new Movie(this, "video.mp4");
      video.play();
    }
    
    void draw() {
      if (video.available()) {
        video.read();
        image(video, 0, 0);
      }
    }

I have “video.mp4” on a folder named data, on the same file as the sketch.
Whenever I try to run the code, I get the following error:

    (java.exe:28748): GLib-CRITICAL **: 19:04:53.545: g_dir_open_with_errno: assertion 'wpath != NULL' failed

I’m using Windows 11. I think the problem is coming from the library instalation, but I’ve asked for friends who have their video working to send me their Processing files, and I’m still getting the same problem. Also deleted everything Processing-related and reinstalled it several times, and I still can’t get it to work. Other libraries such as sound are working.
