I've added a script to my project that has managed to break a different script and I cant fix it

I have a script that makes a particle system start and stop on mouse click and follow the mouse on the screen, and one that causes an asset to rise up from the bottom of the screen (to simulate the particles building up) after I added the mouse follow, the rising assets do not work anymore, I tried removing the mouse follow but they still will not rise!!

This happens when you have an object in the script and that object is doing something, but you didn’t attached object from scene to script in editor.
