OSError: [WinError 259] No more data is available: '(originated from WTSEnumerateSessionsW)'

I tried to limit NCPA agent privilege in Windows server by using local os user for NCPA service.

The following command is what I do:

net user /add nagios Abcd1234
icacls "C:\Program Files\Nagios\NCPA" /grant "nagios:(OI)(CI)RX" /t
icacls "C:\Program Files\Nagios\NCPA\var" /grant "nagios:(OI)F" /t
sc.exe config "NCPA" obj=".\nagios" password="Abcd1234"

### Grant ServiceLogonRight to OS user - nagios
. "C:\Program Files\Nagios\NCPA\plugins\AddServiceLogonRight.ps1"
. "C:\Program Files\Nagios\NCPA\plugins\ListServiceLogonRight.ps1"

The result is positive and functional. But there is only one problem. The following error prompt in 'C:\Program Files\Nagios\NCPA\var\log\ncpa_listener.txt'

2025-03-28 00:23:38,464 listener ERROR [WinError 259] No more data is available: '(originated from WTSEnumerateSessionsW)'

I tried to search the solution in google. But not much reference I can found.
I want to know why ncpa call this function, I didn't monitor Remote Desktop Session in my nagios
