Function cannot be created because function capacity 4096 has been exceeded for this scope

While my problem was solved, I was curious about what module has the highest number of functions and how it was even possible that I could reach this limit. After a simple query as below – it seems the biggest offenders are the newest Microsoft. Graph PowerShell modules that have even 800 functions in one module. Just using a few of those can quickly get you in trouble. Fortunately, I usually use PowerShell 7 as my daily driver unless there's a specific reason not to. Unfortunately, I have other issues with PS 7 that sometimes force me back to PowerShell 5.1, like incompatibility between modules and DLL conflicts. But that's a story for another time.

$Modules = Get-Module -ListAvailable
$ListModules = foreach ($Module in $Modules) {
    [PScustomObject] @{
        Name          = $Module.Name
        Version       = $Module.Version
        FunctionCount = ($Module.ExportedFunctions).Count
    }
}
$ListModules | Sort-Object -Property FunctionCount -Descending | Format-Table -AutoSize
