According to her wiki, she suffered a cardiac arrest while in rehab:

On February 5, 2024, Willis was admitted to a medical facility for critical care in Thousand Oaks, California. In April, her family announced that she was awake after a two-month coma following a cardiac arrest.

In January 2025, her family filed a lawsuit for negligence against Summit Malibu, a rehab in Los Angeles, where Willis was found unconscious for an undetermined amount of time following a brief stay. According to the lawsuit, the lack of oxygen led to irreversible brain damage, which resulted in Willis currently living with locked-in syndrome.
