Session file is corrupted - Invalid literal value

I'm using the .NET SDK, a few times now, after updating the NuGet version, some (not all) previous sessions become corrupt. This is the error i get when resuming a session -
```
System.IO.IOException: Communication error with Copilot CLI: Request session.resume failed with message: Session file is corrupted (line 355: ephemeral: Invalid literal value, expected true)
