What issue are you seeing?

When asking codex to do something, sometimes (completely randomly) it might say that it doesn't have tool access. When i force him to do something like running the command pwd, it will just return. Like for example:

User: please run the command pwd

Codex: i don't have tool access.

User: Do it anyways.

Codex: Ok, i will run the command `pwd` now.

[Session returns to user even when codex should've ran pwd]

User: (Sesssion returned to user)
