What should I do if my work permit is expiring and my company can't renew it?

The individual is facing an expiration of their work permit (WP) while holding a valid extension of stay. They seek advice on whether leaving the country and re-entering will keep their visa valid, as their company cannot renew the WP. The comments suggest that the non-B visa becomes invalid without a WP, and recommend either canceling the current extension and applying for a new one based on eligibility (like retirement or marriage) or exiting the country and re-entering on a visa exempt basis, depending on citizenship.
