Everytime crashes the lab "Reflected XSS with some SVG markup allowed" when payloading it

Hello, I have an issue when I'm trying to do payloading to find XSS valid tags into "<>" tags. Everytime when I try to use Intruder to act the "Sniper" type of attack the server of this lab https://portswigger.net/web-security/cross-site-scripting/contexts/lab-some-svg-markup-allowed crashes and then lab is not loading. It's noticed when the value of "Maximum concurrent requests" more than 1 and then lab crashes. Thank you for your time and hope this issue will be fixed soon.
