Steps to reproduce
It would appear [PSCustomObject] is broken. I realized this because a lot of code stopped working after upgrading to 7.4. In 5.1 same code still works. Consider this test:
Clear-Host
Write-Host ''
Write-Host 'Hash:' -ForegroundColor Green
$newHash = @{
AppId = '12341234'
Version = '23452345'
Name = 'whatever'
Publisher = 'default'
}
$newHash
Write-Host ''
Write-Host 'Object with [PSCustomObject]:' -ForegroundColor Green
$newObject = [PSCustomObject]$newHash
$newObject
Write-Host ''
Write-Host 'Object with New-Object:' -ForegroundColor Green
$newObject = New-Object -TypeName psobject -Property $newHash
$newObject
Write-Host 'Done.' -ForegroundColor Green
Expected behavior
