InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

I created a game with p5 but it gives me error in Mozilla (51.0.1) and can't start game.
This my project.
You can check it on Mozilla.
I get this errors.

[44]</d.Renderer2D.prototype.image 
[56]</e.prototype.image

Unicorn/this.show

bound  self-hosted
[37]</e/this._runIfPreloadsAreDone 
[37]</e/this._decrementPreload 
bound  self-hosted
[56]</e.prototype.loadImage/d.onload 

Why i get this errors?

I looked through the game a bit but it's hard to track down the error because the files are all minified and there's quite a bit of code involved. Because the error mentions loadImage, I might start by confirming that all image files you're loading exist, have the proper read permissions, are correctly named (capitalization too) and are in the right place.

If this doesn't solve anything, I'd suggest commenting out pieces of your code until it runs again in order to identify the problematic line. If you're able to isolate this line, please post it here and we can better figure out where the bug is.

Ah, i figured out now.
I use p5.js gif library and it gives the issuse tho.
I should open this issue there.
Thanks!

Ah ok, glad you tracked it down. Yes, that library is pretty old and I've heard of several issues with it. Hope you can get it fixed over there!
