Thanks for this report. How long does this behavior last for? Does this happen each time you use this feature?

Hi, HTTP Request Smuggler uses Turbo Intruder and there has been a bug reported for extension that causes the UI to lock when you have the .NET Beautifier extension loaded: https://github.com/PortSwigger/turbo-intruder/issues/55 Are you able to remove the .NET Beautifier extension and see if this improves things for you?
