Cursor IDE
Describe the Bug
After using Fable 5 for a few tasks, it consumed 100% of my usage allowance. I switched to Grok to complete the tasks that Fable had started, but since then, I haven’t been able to work properly because I keep receiving the following error:
Request ID: 76b08817-c7b9-4b1d-aa45-3e5fca71169a
A background task finished, but the chat couldn’t resume. Try again in a moment.
