CEM 2 Grasshopper Plugin: CAS-Richtlinie nicht aktiviert

As shown in the screenshot, one of my components (the layout is from the Phoenix3d example file) does not want to run.
The error message (translated to English by me) is here:
“Solution exception:An attempt was made to load an assembly from a network address, which in previous versions of .NET Framework would have resulted in the assembly being executed as a sandbox assembly. In this version of .NET Framework, the CAS policy is not enabled by default, so this load can be dangerous. If you do not intend to create a sandbox assembly through this load process, enable the loadFromRemoteSources switch. Further information can be found at “Bing””

If anybody knows how to solve this, I would be very grateful.
Best wishes.

HI Marlene -
You might want to try to reach the authors of that plug-in, but, from that message, you could try running Rhino 8 in .NET Framework instead of the default .NET Core. Use the SetDotNetRuntime to switch between those. You have to restart Rhino for that to take effect and this might cause other plug-ins to misbehave.
