Bolt.new relies on WebContainers, a browser based runtime from StackBlitz that enables a fullstack development environment in the browser. If you encounter this error, try the following:

• Make sure you are using Chrome or a Chromium based browser as Bolt.new is the most compatible with these environments.
• Selectively disable browser extensions, especially ad blockers, to see if this resolves the issue.
• If accessing bolt.new through a VPN, try again with the VPN disabled.
