You Can Manually Launch Chrome in Debug Mode

open cmd and run "C:\Program Files\Google\Chrome\Application\chrome.exe" --remote-debugging-port=9222 --user-data-dir="C:\Temp\ChromeDebug"

use your own browser path. my one is: "C:\Program Files\Google\Chrome\Application\chrome.exe" then you can run the application and try

This problem will not occur when using an existing browser and setting a separate user-data-dir at the same time. And I started chrome with the command line. It seems that configuring user-data-dir in the web-ui is ineffective
