Windows 11 Task Manager Performance Panel is blank with no data
All data in the Performance tab of Task Manager is blank (CPU, Memory, Disk, etc. are not displayed). Restarting and resetting Task Manager does not resolve the issue. Please provide a fix.

That usually happens if the Diagnostic Policy Service or Performance Counter data is broken. Try this quick fix:
Press Win+R, type services.msc, make sure Diagnostic Policy Service is running.
Open CMD as admin, run:
lodctr /r then restart.
This rebuilds performance counters and should bring Task Manager data back.

A recently installed driver or program might be interfering with performance monitoring. Uninstall any recently added software that might be related to system performance monitoring or hardware.
