Sounds like earlier days of 2022 fob proximity type of logical gate programming bug.
It seems you two and many others reported 50 kW speed when stall is being balance loaded. It could be that EA decided to drop voltage from 1000v to 400v to share load balance charging for all EVs. At 400v, Lucid onboard DC to DC convertor in Wunderbox can only manage to translate to 50 kW max. EA may be doing that to keep load consistent of same voltage. It seems best bet is to charge by at a station by yourself without sharing. Anyway, it’s just my speculation what might happened causing these issues.
