ASP.NET Core 2.1 Web API wont start with Microsoft.AspNetCore.All 2.1.1

I'm debugging my Web API from VS 2017 (15.7.1) and it's working with Microsoft.AspNetCore.All 2.1.0.
But if I update Microsoft.AspNetCore.All to 2.1.1 it wont start up. It doesn't even give me an exception, the console window flashes briefly and then the debugger detaches. Downgrading to 2.1.0 fixes this. No help in Windows event log.

I'm seeing a similar thing.

I manually installed the runtime for 2.1.1
Microsoft.NETCore.App 2.1.1 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
but now I'm seeing this:
MPC> It was not possible to find any compatible framework version
MPC> The specified framework 'Microsoft.AspNetCore.All', version '2.1.1' was not found.
MPC> - Check application dependencies and target a framework version installed at:

The runtime seems to be only in the Microsoft.NETCore.App folder but not in Microsoft.AspNetCore.All

A similar error occurs when using the nuget package for Microsoft.ASPNetCore.App instead of .All

Release 2.1.1 is still being deployed, please use 2.1.0 instead.

The newest SDK (2.1.301) released today fixed my issue.

I'm encountering this issue with 2.1.1 and 2.1.2

Edit: Updating from dotnet core sdk 2.1.300 to 2.1.302 fixes it for me
