Unable to run rules with hashtable that run fine with settings file

[pickscrape]

Steps to reproduce

This is essentially the opposite of #1160

The attached zip file concisely contains the repro:

PSScriptAnalyzerSettingsHashtableRepro.zip

But here it is in plain text too

# repro.ps1

Write-Output "Using settings file"

Invoke-ScriptAnalyzer -Path .\repro.ps1 -Settings '.\PSScriptAnalyzerSettings.psd1'

# Create an unused variable which triggers a warning that the settings file should suppress
$unusedVariable = 1

$settings = Import-PowerShellDataFile -Path '.\PSScriptAnalyzerSettings.psd1'

Write-Output "Loaded settings to hashtable:"

$settings | ConvertTo-Json | Write-Output

Write-Output "Using setting hashtable"

Invoke-ScriptAnalyzer -Path .\repro.ps1 -Settings $settings

# PSScriptAnalyzerSettings.psd1

@{
    ExcludeRules = @(
        'PSUseDeclaredVarsMoreThanAssignments'
    )
}

Expected behavior

The warning should be suppressed in both calls to Invoke-ScriptAnalyzer. Output from the repro script should be this:

Using settings file
Loaded settings to hashtable:
{
    "ExcludeRules":  [
                         "PSUseDeclaredVarsMoreThanAssignments"
                     ]
}
Using setting hashtable

Actual behavior

The warning is only suppressed in the first call (the one that references the file directly). The call that passes the settings hashtable does not suppress the error. Output from the repro script is this:

Using settings file
Loaded settings to hashtable:
{
  "ExcludeRules": [
    "PSUseDeclaredVarsMoreThanAssignments"
  ]
}
Using setting hashtable

RuleName                            Severity     ScriptName Line  Message
--------                            --------     ---------- ----  -------

1.23.0

Note that this issue does NOT happen in this environment (i.e. the warning is suppressed in both calls):

> $PSVersionTable

It appears to be related to the Powershell version.

If I inline the hashtable, it works, therefore there must be something wrong with the way you read the settings file. I don't understand why you'd do that when PSSA allows to just point to the file, are you trying to modify what is in the file?
invoke-scriptanalyzer -scriptdefinition '$a=1' -Settings @{ ExcludeRules = @('PSUseDeclaredVarsMoreThanAssignments' ) }

Fixed in #1967 / PSSA v1.24.0
