[Preview] Never ending formatting

[PrzemyslawKlys]

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.

Summary

I've been coding all day and suddenly - not sure what I did but I couldn't format anymore.

After that - nothing works. Restarting helped

I've had the formatter hang on me a couple times but not for long, worth looking into.

Hi, I'm seeing this exact exception, but intellisense and F8 also stop working when this exception appears in the extension logs:

@PrzemyslawKlys Did you ever fix this problem?

Thanks 🙂

[PrzemyslawKlys]

I use newest preview. Havent had issues since months

[dbrennand]

Hmmm, OK thanks @PrzemyslawKlys - Are you using PowerShell 7.2.6 and may I ask what version of the PSReadLine module do you have?

I read in issue #3393 that PSReadLine may be causing the exception?
