How would you use powershell to check if a net5 dll was compiled in debug or release?

Question

I'm looking for a way to programmatically check with PowerShell if any of my dlls were compiled in debug mode so as not to release an unstable version of my application. I used a similar script to what was suggested here powershell script to check debug mode of dll in specific folder, but when I updated my libraries to net5 I get an exception that says "Could not load file or assembly 'System.Runtime, Version=5.0.0.0, Culture=neutral, PublicKeyToken=blah'" Here is what I was using:

$type = [System.Type]::GetType("System.Diagnostics.DebuggableAttribute")
$isException = $false
$loadFailed = $false

Get-ChildItem -Path $folderPath -Include $include -Recurse |
ForEach-Object {
   $assemblyIsDebug = $false
   try {
      Write-Information "Loading Assembly '$_' ..."
      $loadedAssembly = [Reflection.Assembly]::LoadFile($_.FullName)
      $debugAttribute = $loadedAssembly.GetCustomAttributes($type, $false)
      $assemblyIsDebug = $debugAttribute[0].IsJITOptimizerDisabled -eq $true -and $debugAttribute[0].IsJITTrackingEnabled -eq $true
   } 
   catch [System.Exception] { 
      $loadFailed = $true
      Write-Information "EXCEPTION: $_"
      Write-Information "TRACE:"
      Write-Information $_.ScriptStackTrace
   }  

   If ($assemblyIsDebug) {
      if ($throwErrorOnDebug) {    
         $isException = $true
         Write-Error "File compile mode is DEBUG"
      }
      else {
         Write-Warning "File compile mode is DEBUG"
      }
   }
   Else {
      if ($loadFailed) {    
         Write-Warning "File compile mode is UNKNOWN, assumed to be RELEASE"
      }
      else {
         Write-Information "File compile mode is RELEASE"
      }

Any help would be greatly appreciated!
