无法在 macOS Monterey 上启动 Kestrel

Question

我将我的 macOS Big Sur 升级到 macOS Monterey 然后我尝试运行我的 .Net Core 应用程序 ASPNETCORE_URLS=http://*:5000 配置它给我错误如下

2021-10-27 19:23:25.0068|FATAL|Microsoft.AspNetCore.Server.Kestrel|Unable to start Kestrel.
Unhandled exception. System.IO.IOException: Failed to bind to address http://[::]:5000: address already in use.
 ---> Microsoft.AspNetCore.Connections.AddressInUseException: Address already in use

当我尝试使用以下代码查找监听端口 5000 的人时

sudo lsof -nP -i:5000 | grep LISTEN

结果是；

ControlCe 2874 sametcelikbicak   17u  IPv4 0xac23fd083a725c89      0t0  TCP *:5000 (LISTEN)
ControlCe 2874 sametcelikbicak   18u  IPv6 0xac23fd082e8a6671      0t0  TCP *:5000 (LISTEN)

然后我尝试用 kill 命令杀死那个 listen，如下所示

kill -9 2874

端口侦听不会终止，我再次运行 sudo lsof -nP -i:5000 | grep LISTEN 进行测试，但它再次给了我那个结果

ControlCe 4271 sametcelikbicak   17u  IPv4 0xac23fd0849ef2c59      0t0  TCP *:5000 (LISTEN)
ControlCe 4271 sametcelikbicak   18u  IPv6 0xac23fd083995b411      0t0  TCP *:5000 (LISTEN)

如果我尝试 ASPNETCORE_URLS=http://*:5001 到运行 .Net Core 应用程序它工作，我也重新启动我的 mac 但仍然给出错误，为什么 ASPNETCORE_URLS=http://*:5000 配置不起作用使用 Monterey 并且始终使用端口 5000

还有我的 dotnet 版本和 sdk-list 如下
