In dotnet 8 loading the `System.Data.SqlClient` causes an error when attempting to get the types of that assembly. While this is a known problem attempting to use `Get-Error` to produce more information causes the shell to hang and start to consume all the system resources.\r\n\r\nI've narrowed it down to the formatting of this particular error record in the formatting code https://github.com/PowerShell/PowerShell/blob/b2ba58442353e740d5e2a45a804da6cfef6c21a3/src/System.Management.Automation/FormatAndOutput/DefaultFormatters/PowerShellCore_format_ps1xml.cs#L831. You can run this in pwsh with https://gist.github.com/jborean93/54a9c7fc999b13ddddaf36d716fe7916 to be able to step through the code that hangs. I haven't figured out what property on this particular exception is actually causing the problem but there is something there. My money is on `Types` or `LoaderExceptions` in `$Error[0].Exception.InnerException`.\n\n### Expected behavior\n\n```console\nAdd-Type -Assembly System.Data.SqlClient\r\n\r\n# This will raise an exception\r\n[System.Data.SqlClient.SqlCredential].Assembly.GetTypes()\r\n\r\n# Calling Get-Error after \"hangs\"\r\nGet-Error\n```\n\n\n### Actual behavior\n\n```console\nShows the error without hanging\n```\n\n\n### Error details\n\n```console\nNothing, it hangs\n```\n\n\n### Environment data\n\n```powershell\nName                           Value\r\n----                           -----\r\nPSVersion                      7.4.1\r\nPSEdition                      Core\r\nGitCommitId                    7.4.1\r\nOS                             Arch Linux\r\nPlatform                       Unix\r\nPSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}\r\nPSRemotingProtocolVersion      2.3\r\nSerializationVersion           1.1.0.1\r\nWSManStackVersion              3.0\n```\n\n\n### Visuals\n\n_No response_","author":{"url":"https://github.com/jborean93","@type":"Person","name":"jborean93"},"datePublished":"2024-01-17T00:45:15.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/21083/PowerShell/issues/21083"}
