What issue are you seeing?

After upgrading Codex CLI to 0.142.0, /new and codex resume <session-uuid> both became noticeably slower. They now take about 5 seconds to become usable.

What steps can reproduce the bug?

• Upgrade Codex CLI to 0.142.0.
• Run:

``bash
codex resume <session-uuid>
``

• Observe that resuming the specific session by UUID is very slow.
• Start Codex with codex, then run /new.
• Observe that creating a new session is also very slow.

What is the expected behavior?

• /new should open a new session quickly.
• codex resume <session-uuid> should resume the specified existing session quickly.

Additional information

I previously encountered a similar Codex slowdown, and disabling the apps feature fixed it. After upgrading to 0.142.0, the slowdown is back.
I rolled back Codex CLI from 0.142.0 to 0.141.0, and the issue disappeared. After downgrading to 0.141.0, both /new and codex resume <session-uuid> became responsive again.
So this looks like a regression introduced in 0.142.0.
