Navigating to ASP.NET Core app results in "HTTP Error 502.5 - Process Failure" ErrorCode 0x80004005 : 1

I have a .NET Core 2.1.4 ASP.NET MVC app hosted in IIS (Win 10 OS).

Each time I attempt to access the site in a browser I see this error:

HTTP Error 502.5 - Process Failure

Here is the .NET Core info for my machine:

.NET Core SDK (reflecting any global.json):

Microsoft.NETCore.App 2.1.4 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

In the Event Log the following error is logged:

Application 'MACHINE/WEBROOT/APPHOST/MOTORFINANCE' with physical root 'C:\src\FooSiteProject\Website-FooSite\FooSite\' failed to start process with commandline 'C:\Program Files\dotnet\dotnet.exe .\FooSite.dll', ErrorCode = '0x80004005 : 1.

I'm struggling to find any references to that error code combination 0x80004005 : 1. Is there anyone who can help me out please?

EDIT:

The identity which the app pool runs under, NETWORK SERVICE, does have the required permissions set against the folder where the ASP.NET Core app lives.

EDIT: I earlier installed various .NET Core installers:

• aspnetcore-runtime-2.1.4-win-x64
• dotnet-sdk-2.1.401-win-gs-x64
• dotnet-runtime-2.1.4-win-x64

I executed the iisreset command, but that did not fix the issue. So in response to a comment below, I rebooted the laptop and navigated to the site again. I got the same result, with the same error log in Event Log.

In case this helps, here is a snippet from the web.config relating to aspnetcore

<handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" /> </handlers> <aspNetCore processPath="C:\Program Files\dotnet\dotnet.exe" arguments=".\Foo.dll" stdoutLogEnabled="false" />

There's some exception being thrown at startup, which is preventing your app from successfully starting. Open a command prompt changed to the directory of your published project, and then run dotnet ProjectName.dll. In the console window, you'll be able to see the stack trace for the exception.
