Hello everyone,

I’ve been working on a project for a few days now with no issues using claude 3.5 sonnet as my LLM of choice. It just stopped working for some reason and it says unable to connect to Anthropic. I tried changing the model to o3 to see if it responds but I get unable to connect to OpenAI, I tried switching to the chat LLM to see if its still able to connect and it can without any issues. When I duplicate the workspace to another window and open up a new version of the composer it seems to work without any issues. I’ve given the composer that has crashed a lot of instructions and it knows my project structure extremely well. Is there any way I can get this specific composer to start responding again? I’m new to this app and programming so I really will appreciate any help.

This is my request ID: b80f31b8-6dd1-42f4-b753-3b24895dd5db
