I met the same error and solved it by installing "Computer Vision Toolbox" from "HOME > Add-Ons".
Although it's written in Japanese, I will share the article just in case.
I'm happy if this helps you.

Thanks Masumi! After installing the "Computer Vision Toolbox" the error went away. Now I am facing another one. But, with respect to the Vision Toolbox is good!
Again, thanks!

Hi, your code is almost correct only you have add some pause() between every frame otherwise you won’t be able to see all the frames. The pause time should be ideally 1/FrameRate to view the video in its original speed. Refer to the code below.
vidReader = VideoReader('rhinos.avi'); % Read your video here
vidPlayer = vision.DeployableVideoPlayer;
while(hasFrame(vidReader))
I = readFrame(vidReader);
step(vidPlayer,I);
pause((1/vidReader.FrameRate)); % pause of value (1/FrameRate)
end
implay('rhinos.avi'); % Read your video here
And hit the ‘Play’ button.
Hope this helps!
