PSReadLine crashes on latest build of PowerShell

[kborowinski]

Environment

PSReadLine: 2.2.0-beta2
PowerShell: 7.2.0-preview.5
OS: Microsoft Windows 10.0.19043
BufferWidth: 237
BufferHeight: 9001

Exception report

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.PredictionViewBase.Reset()
   at Microsoft.PowerShell.PSConsoleReadLine.PredictionInlineView.Reset()
   at Microsoft.PowerShell.PSConsoleReadLine.Prediction.Reset()
   at Microsoft.PowerShell.PSConsoleReadLine.Initialize(Runspace runspace, EngineIntrinsics engineIntrinsics)
   at Microsoft.PowerShell.PSConsoleReadLine.ReadLine(Runspace runspace, EngineIntrinsics engineIntrinsics, CancellationToken cancellationToken)

Steps to reproduce

Probable cause

Are recent changes to prediction interface causing this?

Workaround

Rollback PSReadLine module to version 2.1.0 or rollback PowerShell to version 7.2.0-preview.5-46-ge927e94aedb6c425ec98174ac28a1de9feecd72a

Are recent changes to prediction interface causing this?

I think yes. The interface was updated but PSRL is still not. (I guess you could disable the feature in config.)

[kborowinski]

@iSazonov I did disable the prediction with Set-PSReadLineOption -PredictionSource None but it does not help. I'll rollback the PowerShell to version 7.2.0-preview.5-46-ge927e94aedb6c425ec98174ac28a1de9feecd72a and wait for the PSReadLine update.

I ran into the same issue with the latest daily build.

### Environment
PSReadLine: 2.2.0-beta2
PowerShell: 7.2.0-daily20210521.1
OS: Microsoft Windows 10.0.19042
BufferWidth: 160
BufferHeight: 42

Thanks for reporting and using the preview version of PowerShell!
This is a duplicate of #2495. The powershell-7.2.0-preview.6 contains a release note for this:

PSReadLine 2.2.0-beta1 and 2.2.0-beta2 do not work with this preview of PowerShell due to breaking changes in the prediction interface. The upcoming PSReadLine 2.2.0-beta3 release will resolve this. Use PSReadLine 2.1.0 as the temporary workaround.

@daxian-dbw I just grabbed the latest build of PSReadLine from AppVeyor and so far so good! ☺
