The purpose of the wrapper is to decode the results for the version 2019, 2022, but the simple command returns
(Return code of 127 is out of bounds. Check if plugin exists)

Running from service returns no results.

Running from command line:

[root@nagiosxiorcl libexec]# ./check_nrpe -H 10.100.32.15 -t 60 -c Check_OS_Version -2 -a show-all
OK: Windows Server 2016 (10.0.17763)|'version'=100;50;50

[root@nagiosxiorcl libexec]# ./check_nrpe_simple.sh -H 10.100.32.15 -t 60 -c Check_OS_Version -2 -a show-all
OK: Windows Server 2016 (10.0.17763)|'version'=100;50;50

Resolved:
Command definition was defined to run remote.
It needed to run local.

# runs on local host
$USER1$/check_nrpe_wrapper_check_os.sh -H $HOSTADDRESS$ -t 60 -c $ARG1$ $ARG2$
# runs on remote host
$USER1/check_nrpe_wrapper_check_os.sh -H $HOSTADDRESS$ -t 60 -c $ARG1$ $ARG2$

I had not seen this in the documentation but it is working now.
