Got above error recently in my 2023 MG4 Trophy. All was well until I tried to use a slow charger using my own cable on a rainy day. Plugged in...connection error, tried a different unit, same but car also locked itself. Tried a few more times but ended up using a nearby fast charger successfully. After that radio (DAB or FM) didn't work, just got above error message - everything else was fine. Googled it, found suggestion on here to disconnect -ve 12v battery terminal for 30 mins to reboot system.
Did that & when I got back in car, dashboard panel flashed a sequence of messages to wind down driver's/passenger's/ rear right/rear left windows, responded as best I could & end result was radio was now working...but I had multiple messages about traction control/collision system/... not working (7 warning lights on dashboard).
Drove car anyway (short journey) - when I got back in just one dashboard message to wind down rear right window - did that & all OK, no warnings, systems all working.
Can only think that trying to charge using a damp cable had 'shorted' something, disconnecting -ve 12v battery terminal is a good fix & then car will tell you what you need to do to recover - no settings were lost as a consequence of this.
