### Prerequisites

- [x] Write a descriptive title.
- [x] Make sure you are able to repro it on the [latest released version](https://github.com/PowerShell/PowerShell/releases)
- [x] Search the existing issues.
- [x] Refer to the [FAQ](https://github.com/PowerShell/PowerShell/blob/master/docs/FAQ.md).
- [x] Refer to [Differences between Windows PowerShell 5.1 and PowerShell](https://learn.microsoft.com/powershell/scripting/whats-new/differences-from-windows-powershell).

### Steps to reproduce

This is stripped-down function that allows for successful repro of PowerShell crash on tab completion:

```powershell
enum Reboot {Pending; Unneeded}

function Get-Reboot {
    [CmdletBinding()]
    param(
        [Reboot]$Reboot
    )

    $status = @{}

    $data = @(
        @{Name='Server1'; Status='Pending'},
        @{Name='Server2'; Status='Unneeded'}
    )

    $data.ForEach{
        $status.Add($_.Name, $_.Status)
    }

    switch ($Reboot) {
        'Pending'   {
            $data = $data.Where{
                $status[$_.Name] -eq 'Pending'
            }
            break
        }
        'Unneeded'  {
            $data = $data.Where{
                $status[$_.Name] -eq 'Unneeded'
            }
            break
        }
    }

    $data |
        Sort-Object -Property Name |
        Select-Object -ExpandProperty Name
}
```

1. Save the function to a file and dot-source it.
2. `Get-Reboot | % {$_.<TabComplete>`



### Expected behavior

```console
PowerShell should not crash
```

### Actual behavior

```console
PowerShell is crashing
```
