Sonnet 3.5 suddenly not working

I was having a normal dev session when suddenly chat with sonnet stopped working. If I change to chatgpt it works, but… I rather use Claude. This happened yesterday and the issue still is going on.

Anyone else having the issue or know what the reason can be?

Thanks

New findings:
Is project related, as another project is working no problem.

PS: there is at least another user in reddit with the same issue.

thanks!

edit: copy/pasting the project folder and opening the copy doesn’t fix it.

Hmm, could it be that this is a large project? In any case, the error is not clear. How many lines are in the file you’re working on? Has your project been fully scanned, or does it contain errors as well? Does the same thing happen with other models? Maybe you should try using a model with a long context chat?

new chat with long context fixed it, thanks!

Cool :+1:
