我正在构建flutter网站项目，并通过firebase启用登录页面后，我运行了flutter run -d chrome。但是它在尝试连接浏览器时被卡住了，它只是尝试了无休止的时间而没有给出任何错误消息。状态栏：

λ flutter run -d chrome
Launching lib\main.dart on Chrome in debug mode...
Building application for the web...                                20,2s
Attempting to connect to browser instance..                             
(This is taking an unexpectedly long time.)       \

Flutter doctor:

λ flutter doctor
