Issue: On MacOS using JetBrains Rider when I try to Run Project or Rebuild Solution using .NET 5 ocassionally (but often, after 7-8 runs/build) the run/build freezes and after 15-20 seconds the following error occurs:
"Can't connect to protocol model"

Troubleshooting performed: When I TURN OFF the Avast Security FILE SHIELD the issue IS SOLVED. Having File Shield ON, and adding exception path for:

/Users/my.username/Projects/ - my .NET projects folder
/usr/local/share/dotnet/ - .NET SDK and Runtime folder

DOES NOT resolve the problem.


For now I'm using the workaround with Filed Shield OFF. Let me know if any Avast Security logs are needed (describe how to get the logs).
