Broken state when using Claude models

[mk1123]

Hi. I intermittently find myself in a state when I'm using Claude models in which no matter what I type, I always receive the following string as the response:

messages: text content blocks must be non-empty

I haven't been able to reproduce the steps I took to get into this state, but it's frustrating because I don't know how to get out of this state other than completely redownloading the app and setting up everything from scratch. Could you take a look at this bug and fix it? Thanks.
