We need repo.

Can you open this in the PSReadLine repo? PSConsoleReadLine is coming from PSReadLine

[iSazonov]

@daxian-dbw Could you please make a conclusion about the issue while you is on the wave?

[daxian-dbw]

@iSazonov I cannot. I cannot reproduce this, and the reported exception was thrown from the .NET Core code. Hope it's fixed in the .NET Core 3.0

They say that it is terminal issue. I guess VS Code terminal.

We could close the issue until we get stable repo.

[daxian-dbw]

Close the issue because

1. cannot reproduce the issue
2. exception is thrown from System.Console.ReadKey, which is .NET Core code.

This problem could be caused by: dotnet/runtime#88697

I plan to open a new Issue for how this could be addressed in PSReadLine.
