Questions :

When executing cmd1, it is always impossible to execute on a Linux server, but when CMD2 is executed, it can be performed normally on a Linux server. If there is no quotation mark, there is a problem when there are special characters in the argument, there is a failure of execution or the parameter is different from the original parameter.

There is no better workaround for the time being, instead the command is executed using the existing incoming array method.
