Versy confusing argumentoutofrangeexception error

After loading up my project today, my computer spat out this:

I am very unsure of what I did for this to happen, as the last thing I did in my code was add comments to describe what was happening.

It looks like you have build your game into your assets folder. NEVER do this.

The assets folder is only for assets that belong to your project. You can create a “builds” folder next to the Assets folder inside your project folder. Any file inside the Assets folder will be imported ny Unity into your project.

Just to make that clear: You have to remove the builds you currently have inside your Assets folder. That should fix the problems you have.
