请详细说明你的开发环境，运行的例程，和问题复现的过程，以及报错的 log。

使用的是VSDODE，运行的是usb-cdc-4g-module，在网页端修改wifi账号密码时有时出现死机，有时会出现如下报错

可能是 4g 模组突然的大电流导致芯片掉电，建议单独给 4g 模组供电。

[dahwgdg]

但是其他功能都是正常的

[dahwgdg]

芯片没有掉电

[lijunru-hub]

可以试一下不接 4g 模组，修改网页配置

[dahwgdg]

直接修改网页配置也是没有更改，更改完重启，下面是日志

I have tested the example, and it allows you to change the username and password via the web interface. Do you have any further questions regarding this example? If not, I will proceed to close this issue.
