import-module with $MaximumFunctionCount = 32768 fails in PowerShell 5.1

[Tarjei-stavanger]

Describe the bug

import-module microsoft.graph with $MaximumFunctionCount = 32768 fails in PowerShell 5.1 when the variable is set in the script, but works fine if it is done on the command line.

##
## Setting in script
##

if ( 32768 -gt $MaximumVariableCount ) {

    $MaximumVariableCount = 32768;

};

if ( 32768 -gt $MaximumFunctionCount ) {

    $MaximumFunctionCount = 32768;

};

"MaximumVariableCount $MaximumVariableCount ";
"MaximumFunctionCount $MaximumFunctionCount";

Command line.

Script display unfortunately with error messages in Norwegian. But you get the drift.

BTW. I know this works fine in PowerShell 7.x, but those who run this might not have that installed.


### Expected behavior

That import-module works the same whether it is a script or on command line in PowerShell 5.1.

### How to reproduce

Run script or copy commands from script to command line.
