NCrunch can't build my core2.2 solution

Hey everyone,

I really hope to find some help here, as it took me hours to probably solve my problem with no luck.

NCrunch Version: 3.22.0.1
VS Version: VS2017 15.9.3
By-Side Installation: R#

Problem:
Ncrunch can't built the solution.

2 colleagues have similar setups - all fine there. We find no differences in configuration and the like.
I already tried to reinstall the whole setup - no success.

Stacktrace

System.Exception: An exception was thrown in the remote environment: System.Reflection.TargetInvocationException: Ein Aufrufziel hat einen Ausnahmefehler verursacht. ---> nCrunch.Common.UserException: Errors occurred while trying to load the project file: 
Die Ressourcendatei "C:\Sources\platform\Softfair.Kolumbus\src\Softfair.Kolumbus.Host\obj\project.assets.json" verfügt über kein Ziel für ".NETCoreApp,Version=v2.2/win-x64". Stellen Sie sicher, dass die Wiederherstellung ausgeführt wurde, und dass Sie "netcoreapp2.2" in die TargetFrameworks für Ihr Projekt aufgenommen haben. Unter Umständen müssen Sie auch "win-x64" in die RuntimeIdentifiers Ihres Projekts aufnehmen.

Hi, thanks for sharing this problem.

This is an error being raised by MSBuild when NCrunch tries to load the project file. Something is not right with the project.assets.json file inside the project's directory. Try deleting ALL the 'bin' and 'obj' directories for ALL your solutions while you have the IDE closed. The next time you open the solution, the IDE should restore the file in a hopefully uncorrupted state.
