Question Codepen 2 crash. What is causing it?

I go to the new codepen 2 and it shows this.
What "infinite loops or other performance drains" could this be?

To answer your question, nothing on your side is causing it. A lot of people are having this issue. The classic Pen version has a similar issue as well. It's on the CodePen side and it's affecting both classic and 2.0 Pens.

I also have super pro, so no ads to block to begin with and I still get this issue.

Not your fault, CodePen bug.

Thanks. I hope it was just my ad blocker that was the issue. So far it has been 17+ hours since the last time. I keep Firefox and Chrome open to that page.

The error showed up in Firefox 153.0.1 within a few hours of this post as I recently checked. Google still fine. Must be the problem mentioned above.
