Csharp 无法运行 Docker .NET 6 控制台映像

嗨，我有下面的.NET6控制台应用程序的dockerfile

FROM mcr.microsoft.com/dotnet/runtime:6.0 AS base
WORKDIR /app
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY ["MyProj/MyProj.csproj", "MyProj/"]
RUN dotnet restore "MyProj/MyProj.csproj"
COPY . .
WORKDIR "/src/MyProj"
RUN dotnet build "MyProj.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "MyProj.csproj" -c Release -o /app/publish /p:UseAppHost=false

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "MyProj.dll"]

我正在使用GitHub Actions CI工具来构建映像并将其部署在kubernet中.我在构建时没有收到任何错误，但当映像运行时，我收到以下错误

You must install or update .NET to run this application.

App: /app/AL.AlphaLinerJob.dll

下面是csproj包

        <PackageReference Include="prometheus-net.AspNetCore" Version="7.0.0" />
        <PackageReference Include="Npgsql" Version="7.0.2" />

我找不到它的根本原因.几天前它工作得很好，突然开始出现这个错误.有人能帮我找出根本原因吗？任何帮助都将不胜感激.

我希望能成功运行该映像.
