Hello there. This problem resurfaced when I updated Powershell to v7.2.0. The following error prompts when I start my terminal.
Environment

PSReadLine: 2.2.0-beta1 PowerShell: 7.2.0 OS: Microsoft Windows 10.0.22000 BufferWidth: 123 BufferHeight: 30 Last 0 Keys

Exception
System.TypeLoadException: Could not load type 'System.Management.Automation.Subsystem.PredictionResult' from assembly 'Microsoft.PowerShell.PSReadLine.Polyfiller, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

   at Microsoft.PowerShell.PSConsoleReadLine.ReadLine(Runspace runspace, EngineIntrinsics engineIntrinsics, CancellationToken cancellationToken)
The following is my Powershell Profile:-

oh-my-posh --init --shell pwsh --config D:\External-GitHub-Repos\github\prompt\ohmyposhv2.json | Invoke-Expression Import-Module -Name Terminal-Icons Import-Module z Import-Module PSReadLine Set-PSReadLineOption -PredictionSource History Set-PSReadLineOption -PredictionViewStyle ListView Set-PSReadLineOption -EditMode Windows
Managed to solve this by updating the PSReadLine module to v2.2.0-beta4. 🥳

I got the same error: Install-Module PSReadLine -AllowPrerelease -Force fixed it - From Scott Hanselman’s Blog: (https://www.hanselman.com/blog/powershell-720-could-not-load-type-systemmanagementautomationsubsystempredictionresult?utm_source=feedly&utm_medium=webfeeds)
