Not sure if this will help, but you might also try going to the charging menu, then hit the settings button in the upper right, then press "reset" at the bottom of the popup screen to reset the current limiter settings. FWIW, I regularly charge at 80A/19kw using the Lucid high-power charger, and I have never had an issue.
What EVSE are you using? I had problems with my old Tesla 80A HPWC; it never worked at all with Gravity and I had to swap it out. I'm not sure why this happened, as AC charging is still handled through J1772, which was the same back then. Still works OK on my wife's Air, though.
