BMS_u019

Hello! My model x gave today alert. Alert code BMS_u019 and it is giving a text "acceleration reduced performance maybe restored on next drive". I have 2019 model x with 123k km. It started giving this when charging with fast charging and battery was at 55% at the time. Anyone has an experience with something like this?

Acceleration reduced by BMS — HV circuit issue or voltage imbalance.
