DotNetty .net7.0 published Aot ok, but error to run examples/Echo.Server

(1) I changed all the dotnetty .csproj files
changed TargetFrameworks to net7.0
added PublishAot

` `
` Exe `
` net7.0 `
` false `
` Debug;Release;Package `
` AnyCPU`
` true`
` `

(2) Compiled examples/Echo.Server as debug / release version, run Echo.Server.exe, everything was OK
OK

appsettings.json
{
"ssl": "false",
"port": "28007",
"libuv": "false"
}

(3) Published the project win-x64 OK.
But there was error to run the Echo.Server.exe
