What's Wrong?

The CoworkVMService source is flooding the Windows Application Event Log with Information-level events at an extremely high rate. As of today, over 56,000 events have been logged, with multiple entries per second (e.g., 9+ events per second).

What Should Happen?

Claude should not be creating entries in the event log at this rate
