• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macOS 26.6.0 (25G5028f)

Expected behaviour

After upgrading to MacOS 26.6 Beta (25G5028f) Kiro should be working in Ghostty

Actual behaviour

After upgrading to MacOS 26.6 Beta (25G5028f) Kiro does no longer work in Ghostty. This actually seems to be more global as it also does not work in iTerm2 and cmux.
The issue won't solve event after calling kiro-cli integrations install input-method and restarting the terminal
and kiro-cli doctor returns the following:
✔ Everything looks good!
Kiro CLI still not working? Run kiro-cli issue to let us know!

Steps to reproduce

Upgrade to MacOS 26.6 Beta (25G5028f)
