    The "Kernel-EventTracing 3 Session" error logged in your system event logs indicates an issue related to Kernel Event Tracing (ETW) sessions. ETW is a high-performance, low-overhead tracing mechanism used by Windows to log system, kernel, and application events for diagnostics and performance analysis.
