gifplayer | Customizable jquery plugin to play and stop animated gifs | Animation library

I am trying to create a simple GIFPlayer which shows GIF if someone clicks on a play button otherwise shows a PNG like:

I have a div that shows gif image and I have 4 gif image to cycle through with different duration in an endless loop(gif should cycle through 1 2 3 4 then 1 2 3 4 endlessly)

My gifplayer div: Other than the first div the other 4 divs initial display property is set to none

First of all, I want to apologize for the very long question but this is driving me crazy. Saturday I have to exhibit this project to my school's open day and I have little to no time.

I've written a snake game in Python 3.9 with a friend (using Pygame) and I'm trying to create an executable file with PyInstaller from it (using multiple python modules and additional files such as images and music), but every time I execute the command pyinstaller Game.spec and I try to run the executable I get this error:

This error is very unexpected and strange to me because I already made it executable about a week ago (but it was an older version and we change lots of things) in the same way and it worked flawlessly, but now it won't work in any way, we tried everything and read every post here on Stack, so the executable gets created but it won't start.

We changed really a lot of things since we made the first executable, but the structure of the code remained pretty much the same with the only exception of a module that I wrote, basically it automatically splits animated GIFs into separated frames and loads them into Pygame (loading every single frame by hand was too time-wasting...). I suspect that this module might be one of the causes that ultimately lead to prompting that error every time I try to execute the game. We used this module to animate the buttons in the main menu:
