Bug Description

The most recent updates (for approximately the past week), are consistently hanging inside Claude Code. Pressing any key while it is "thinking" results in it being placed into a background process and when typing fg to put it back into the foreground, it hangs and puts out escape codes in the terminal.

Steps to Reproduce

1. Run Claude Code
2. Give it any longer task (>30 seconds)
3. Let it run and it hangs.

Expected Behavior

It should not hang and place itself in background. When I use the models from cursor, windsurf or the Claude App, I do not see anything like this behavior

Actual Behavior

Described above

Additional Context

This is all recent behavior so it must have been introduced with the within the past week or so.
