While refactoring the code into a while loop, the previous early return when no frame exists went missing. We have just printed a message that we cannot get information about this, so the frame will be None, and we cannot attempt to use it. Discovered on python 3.11, in python 3.12a2 this should error out with `.is_shim()` instead of `co_name`. (cherry picked from commit 85869498331f7020e18bb243c89cd694f674b911)

Regression in commit b4903afd4debbbd71dc49a2c8fefa74a3b6c6832. While
refactoring the code into a while loop, the previous early return when
no frame exists went missing. We have just printed a message that we
cannot get information about this, so the frame will be None, and we
cannot attempt to use it.

Discovered on python 3.11, in python 3.12a2 this should error out with
`.is_shim()` instead of `co_name`.
