puppeteer: puppeteer 9.1.0 broken: "target should exist before targetInfoChanged"

Steps to reproduce

Unfortunately I can’t provide a test case. However I can say that 9.0.0 works every time, and 9.1.0 fails every time.

Tell us about your environment:

• Puppeteer version: 9.1.0
• Platform / OS version: Windows 10 or Ubuntu 20.04.2 or Amazon Linux 2
• URLs (if applicable):
• Node.js version: 15.14.0

What happens instead?

Puppeteer crashes with the following message:

        throw new Error(message);
