Missing Tool Result Block for Tool Use ID toolu_0177ZD9Sd6uNJc9HjvEQTrCR #2179

Description

@danielcor

This is a repeated issue, when I press ESCAPE to interrupt Claude so that I can add another prompt to correct something it's doing wrong, often, i get this error after, and have to restart Claude when this happens.

It's pretty easy to reproduce... what else do you need to help isolate the issue?
