I am getting this error on multiple servers while installing CU22, please can someone suggest :
Performance counter names and help text failed to unload. Unlodctr exited with error code '1224'.
Event viewer is showing alerts for different Exchange counters on different servers, for example :
Unloading the performance counter strings for service MSExchange AD Performance (MSExchange AD Performance) failed. The first DWORD in the Data section contains the error code.
I have tried lodctr /r , updating, unloading, regkeys etc but it does not help, anyone else encountered this ?

What is the current CU version of your Exchange servers?
Please run this script to check the prerequisites: SetupAssist.ps1
Would the result show some permission errors?
Hi KaelYao,
Current CU is CU20.
I have already checked the prereqs and the CU22 worked fine for some of the servers but not all, on a few servers its not proceeding after step 6 of language services and giving the error above for perf counters.
No permission errors as well.
Here are some details from setup logs :
[1] Updating performance counter strings for WorkloadManagementPerformanceCounters.ini
[1] Updating performance counter strings for WorkloadPerformanceCounters.ini
[1] Updating performance counter strings for WsPerformanceCounters.ini
[1] Finished updating performance counter strings
[1] [ERROR] Performance counter names and help text failed to unload. Unlodctr exited with error code '1224'.
[1] [ERROR] Performance counter names and help text failed to unload. Unlodctr exited with error code '1224'.
[1] [ERROR] Performance counter names and help text failed to unload. Unlodctr exited with error code '1224'
Kindly suggest.
Please run Powershell in administrator and add the Exchange Snap-in (add-pssnapin Microsoft.Exchange.Management.PowerShell.Setup)
Then run the following script to rebuild the Exchange performance counters and see if it can help with this issue:
$path = "C:\Program Files\Microsoft\Exchange Server\V15\Setup\Perf"
$items = Get-ChildItem -Recurse $path
$files = $items | ?{$_.extension -eq ".xml"}
Write-Host "Registering all perfmon counters in $path"
Write-Host
$count = 0;
foreach ($i in $files)
{
$count++
$f = $i.directory, "\", $i.name -join ""
Write-Host $count $f
New-PerfCounters -DefinitionFileName $f
}
Another update - Experienced same issue while upgrading to CU23 for Exchange 2016 : Fix was to disable Antivirus and "lodctr /r" from elevated cmd.
Hope it helps someone in need.

Solution:
Restored the VM from backup, to bring it back to original state (previous CU installation),
Uninstalled all windows updates from past few days
Started all Exchange services manually multiple times while latest CU upgrade was in progress. (Including winmgmt, W3Svc, IIS, filtering and Net.Tcp port sharing service).
Installed latest CU and Security updates
Updated\patched windows again.
Rebooted and worked.
Thanks @KaelYao-M
Tried manual addition\registration\rebuilding of perf counter with no help
Tried windows updates, multiple reboots, event log error searches and fixes with no help
Tried multiple available scripts around this issue on web from our Exchange colleagues , but did not have any luck

Restored the VM from backup, to bring it back to original state (previous CU installation),
