Another comment - the git autocomplete is posh-git

This is a very strange issue. I cannot reason from the ReadOneOrMoreKeys method about when it would return with an empty _queuedKeys. Seems impossible to me ...

You mentioned in the windows terminal issue that you pressed Alt+Pause to break out of the unresponsive git log. Did you then, as indicated by your screenshot, start to debug a PowerShell script and press Alt+Pause again which led to the exception? I ask this because your last 200 keys shows Alt+Pause as the last input.

Yes, this is the sequence - pressing Alt-Pause to break out and again (for no reason :) ) and getting the error

Adding to this one. Happens when during debug in VSCode and while trying to type something.

@PrzemyslawKlys, the issue you run into is in VSCode. That's tracked by #3292 and will be fixed by #3294.
