Solution Steps

  1. 1 Press Ctrl+Shift+Esc to open Task Manager. Go to the 'Details' tab. Look for processes like 'WPR' (Windows Performance Recorder), 'VSPerf', or any process related to your profiling tool. Right-click and select 'End task'. This forcefully stops the profiling session if it's stuck.
  2. 2 Press Windows key + R, type 'cmd', and press Ctrl+Shift+Enter to run as administrator. Type 'wpr -cancel' and press Enter. This command cancels any ongoing Windows Performance Recorder session. If you're using a different tool, check its documentation for a similar cancel command.
  3. 3 Open Services (Win+R, type 'services.msc'). Find 'Performance Logs & Alerts'. Right-click and select 'Restart'. This resets the service, clearing any stuck state.
  4. 4 If the above doesn't work, press Windows key + X and select 'Terminal (Admin)'. Type 'taskkill /f /im wpr.exe' (or the executable name of your profiling tool) and press Enter. This force-kills the process. Be careful: this will lose any unsaved profiling data.
  5. 5 Reboot your computer to ensure all profiling sessions are fully terminated. After reboot, try starting a new profiling session to verify the error is gone.
