: Some antivirus software may block or conflict with Event Tracing for Windows (ETW) sessions.
Then restart your computer.
To solve the problem, we first need to understand the components involved. This public link is valid for 7 days

Yes. Microsoft occasionally releases updates that introduce new diagnostic logging sessions. If an update does not properly clean up an old session, a name collision can occur with the next update, resulting in the 0xc0000035 error. This usually resolves itself after future updates.
Remember: In Windows, 0xc0000035 isn't a death sentence—it's just a collision. Clear the road, and updates will flow again. Can’t copy the link right now
If the ETW session cannot be stopped because it is in a "zombie" state (linked to a dead process), you may need to reset all Windows Update components. This is a broader fix, but it will clear the trace collision.
This means that the Kernel Event Tracer tried to spin up a new logging session using a specific name or identifier, but another active process or an orphaned registry key was already using that exact same name or memory space. Because two items cannot share the same identifier, the startup sequence fails and triggers the event log entry. Common Causes of the Error
Since the error stems directly from the Windows Update tracing mechanism, purging the update cache usually clears the conflict. Then restart your computer
After some research, I found that error translates to ERROR_ALREADY_EXISTS — meaning the trace session is already running or another process has a conflicting handle.
