TL;DR

The issue with "Failed to read thread goal: thread/goal/get failed in TUI" in Codex CLI 0.128.0 may be resolved by checking the thread ID and ensuring the model and subscription are compatible.

Guidance

• Verify that the thread ID 019debd9-2372-7f23-92b9-9f34002a6355 is correct and exists in the system.
• Check the compatibility of the gpt-5.5 model with the pro 5x subscription to ensure it is supported.
• Review the terminal emulator cursor settings to ensure it is not interfering with the Codex CLI output.
• Try running the command with a different model or subscription to isolate the issue.
