@kiddliu Thanks for reporting the issue. You mentioned with Runtime 114 it worked, was it on the same OS version?

@novac42 for my case I cannot say for sure, but later after confirmed with my colleagues, I'm not the only one with this problem. We're all on Windows 11, but with different builds: 22621, 25921.

Another possible useful information is that Lighthouse also not works on Microsoft Edge v115.

That's probably the underlying issue. I'm going to add this bug to our backlog and check with the DevTools team if this is a known issue they're already looking into. Thanks!
