An action may not be commenced in any event more than 6 years after the date the professional services were performed.(e) If the person entitled to bring the action is under the age of  majority or under other legal disability at the time the cause of action  accrues, the period of limitations shall not begin to run until majority is  attained or the disability is removed.(f) If the person  entitled to bring an action described in this Section is not under a legal disability at the time the cause of action accrues, but  becomes under a legal disability before the period of limitations otherwise runs, the period of limitations is stayed until the disability is removed. This subsection (f) does not invalidate any statute of repose provisions contained in this Section. This subsection (f) applies to actions commenced or pending on or after January 1, 2015 (the effective date of Public Act 98-1077).(g) This Section applies to any cause of action, regardless of the date the cause of action arises. This Section, however, does not bar the filing of an action based on the performance of professional services before the effective date of this amendatory Act of the 102nd General Assembly if the action is timely filed under the version of this Section in effect on January 1, 2021, and is filed within a reasonable period, not to exceed 6 years, after the effective date of this amendatory Act of the 102nd General Assembly.
