Chip-8-Emulator | A Chip-8 Emulator | Emulator library

I am new to emulation and figured writing a CHIP-8 interpreter would get be started. However, I am facing an issue. When running a game, like Brix for example, it draws the game no problem (the paddle, etc.) but, after it is done, it just gets stuck in a loop of 0x3000 and after that, a jump instruction that jumps back to the 0x3000. It is clear that 0x3000 is false and that is why it is looping, but I can't figure why that is for the life of me.

Screenshot of the game and the Chrome devtools console (the game is Brix, taken from here): https://i.stack.imgur.com/a0wNM.png

In that screenshot, in the console, you can see the 0x3000 is failing and going to a jump, and that jump goes back to 0x3000, and the cycle repeats. This happens with most, if not all games. I suspect is has something to do with the delay timer, since 0x3000 is checking for v0 === 0, but it fails, and goes to the jump instruction.

Here is my main CHIP-8 class:
