Error handling issue

Hello,

I have a global misunderstanding about error handling. If I start some cmdlet that repeats some steps (classic pipeline for example) and one instance here drops an error but I want to ignore this error why cannot I do this:

    $error.Clear()
    Get-ChildItem ${env:ProgramFiles(x86)} -ErrorVariable $null -ErrorAction SilentlyContinue -Recurse | Where-Object {$_.Name -match "1.exe"} 
    $error[0]

The error always shows:

Get-ChildItem : Access to the path 'C:\Program Files (x86)\Google\CrashReports' is denied.
At line:2 char:5
+     Get-ChildItem ${env:ProgramFiles(x86)} -ErrorVariable $null -Erro ...
