#Error

This error seemingly randomly occurs. All that pops up is a ton of numbers, and without a screenshot, all I remember is the end, which is -3. No, it doesn't say client error anywhere in it. It just has a bunch of numbers come up and then I have to alt tab to close the game. At first I thought it could have been because of my MP5, but it just happened while using AK-Silver.

If anyone has any clues on what this is, it would be nice to get some help. Also, I will try and edit and get a screenshot or video of it. If need be, I will make a new post.
