The problem is the combination of Bun and Playwright, right? If so I think we should be more forgiving and log a warning to that effect (instead of throwing) and also give users the option to turn off the warning, e.g.
"WARNING: if you are using Playwright with Bun you will not be able to connect over CDP: {link to GitHub issue}.
Turn off this warning with KERNEL_BUN_WARNING=off"
