When I bought my 2022 AGT in October 2022, I was able to charge at the DCFC stations, but it will not charge at my home with L2. A mobile tech came by my house and told me my L2 receptable needs to be upgraded to the Hubbell receptacles. I did that, but the problem persisted. To make a long story short, after multiple visits to the Lucid SC and exchanged chargers and cables, Lucid concluded it was a Wuderbox problem. It made sense, as (like yours) the car charges with DCFC, but not with AC home chargers.
So, Lucid took my car for 2 weeks, replaced the Wunderbox and the battery. Thereafter, everything worked.
I am NOT saying you have the same problem. But the symptoms are similar. But, it can also be a SW problem.
