This issue might be a duplicate of existing issues related to the prompt component and TUI crashes. Please check:

• opentui: fatal: undefined is not an object (evaluating 'local.agent.current().name') #7727: opentui: fatal: undefined is not an object (evaluating 'local.agent.current().name')
• opentui: TUI crashes after successful native OpenAI account connection (TypeError: local.agent.current() is undefined) #7550: opentui: TUI crashes after successful native OpenAI account connection (TypeError: local.agent.current() is undefined)
• opentui: fatal: undefined is not an object (evaluating 'local.agent.current().name') #7630: opentui: fatal: undefined is not an object (evaluating 'local.agent.current().name')
• opentui: fatal: undefined is not an object (evaluating 'local.agent.current().name') - When login copilot #7628: opentui: fatal: undefined is not an object (evaluating 'local.agent.current().name') - When login copilot

These all show similar "undefined is not an object" errors in the prompt component (src/cli/cmd/tui/component/prompt/index.tsx), though with different expressions being evaluated. The pattern suggests a common underlying issue with component state or ref initialization in the prompt component.

Feel free to ignore if your specific case (forking a session during plan execution) has a unique cause, but these issues may share the same root cause.
