Environment data

PS Version: 7.4.1
PS HostName: ConsoleHost (Windows Terminal)
PSReadLine Version: 2.3.4
PSReadLine EditMode: Windows
OS: 10.0.22621.1 (WinBuild.160101.0800)
BufferWidth: 163
BufferHeight: 45

Steps to reproduce

I would like to run a small init script before a PowerShell session starts to access PSReadLine command history there. Unfortunately, [Microsoft.PowerShell.PSConsoleReadLine]::GetHistoryItems() fails with the error.

pwsh.exe -NoExit -ExecutionPolicy Bypass -File .\init.ps1
#init.ps1
if (Get-Module -Name PSReadLine) {
  $HistoryItems=[Microsoft.PowerShell.PSConsoleReadLine]::GetHistoryItems()
  if ($HistoryItems -eq $null) {
    [Console]::WriteLine("got null")
  }
  else {
    [Console]::WriteLine("got not-null")
  }
}

Expected behavior

History items can be accessed successfully, no exception happens and not null is printed to the console.

Actual behavior

Please note that if I run the same script inside PowerShell session, GetHistoryItems() works fine. But I need to run it in the init.ps1 script passed as described above. Please let me know if there is a workaround. Thanks!
