I suspect you need to publish as a self contained app.

I imagine you're publishing to Azure? Which does not yet (AFAIK) have the dotnet core 3 runtime, so you need to publish with the runtime.

If you are doing this from visual studio, you select publish as self contained

@overstartup If you've published your app as self-contained, There's file named Web.Config. If you're using .Net Core 2.2, few lines of web.config file are like photo below:

In this case remove V2 from modules="AspNetCoreModuleV2" and save the config file, then restart you app.
