C# debugging

Hi,
after deleting the working previous version of the PLCnext toolchain for Windows (C++/C#) I installed the lates one (PLCnext_Toolchain_Windows_2022.0). Now, when trying to attach to process, I don’t get the connection type eCLR any more.
What did I miss to setup?
Best regards Götz

VS must be launched as administrator, then it works.
