   @joye1230 how did you install .NET? Can you run dotnet --info at all?

   Since this is an unable to spawn CoreCLR error I will transfer to runtime.

    The next steps the runtime team would probably need to diagnose this is a corehost trace logging what the runtime was attempting to load.

    The app that I am working on is also experiencing this issue. I've sent the trace to @agocke and provided more info to him offline.

    @joye1230 @thinhunan @Stardito can you check the entitlements of your app executable?

    @jtschuster investigated @fanyang-mono's repro which ended up being due to missing entitlements:

    • Codesigning the apphost on macOS should preserve entitlements #113707

    The workaround would be to explicitly re-add the entitlements.
