### FAQ

- [x] Yes, my issue is not about [variability](https://github.com/GoogleChrome/lighthouse/blob/main/docs/variability.md) or [throttling](https://github.com/GoogleChrome/lighthouse/blob/main/docs/throttling.md).

### URL

https://hermesnovin.com

### What happened?

When I try to run a Lighthouse audit for https://hermesnovin.com using Chrome DevTools, the report does not start or complete successfully.

Lighthouse displays an execution error related to Chrome or DevTools instead of generating the audit report. The website itself is publicly accessible and loads normally in Chrome.

The issue occurs when starting the Lighthouse analysis from the Lighthouse panel in Chrome DevTools.

### What did you expect?

I expected Lighthouse to successfully analyse the page and generate a complete report containing the Performance, Accessibility, Best Practices and SEO results.

### What have you tried?

I have tried the following troubleshooting steps:

Reloaded the website and attempted the audit again.
Closed and reopened Chrome DevTools.
Restarted Chrome.
Tested the website in an Incognito window.
Disabled browser extensions.
Cleared the browser cache.
Confirmed that https://hermesnovin.com is publicly accessible and loads correctly.
Tried running the audit again from the Lighthouse panel.

The Lighthouse report still fails to run.

### How were you running Lighthouse?
