Please help

Hope someone can assist.
I have inherited a 2015 leaf. Unfortunately I don’t know its history or how this fault came about.
The car arrived with a flat 12v and would not start, or charge. Swapped for a new battery. Same issue. I ordered LeafSpy and read / cleared the faults and checked the battery. ( faults below )
Now the car drives fine, stops, starts, turns off and on fine. When it come to charging, it starts and after around 30seconds the blue lights go out, a click, and the car throws the same fault, clear the codes all is well.
This is on the granny.
On a house charger it tripped the main house breaker.

I now only have enough charge to get to a chademo charger, in the hope this will charge without the fault.

I also noticed the battery charge numbers look odd, it also has 12 bars on the battery health.

Desperate to get this fixed asap.

Thanks

A coupla things I see, one doesn't make much sense.
50K miles and 15 qc and 15 L1/L2 charges. Not nearly enough charges for the miles.
Next, the trouble codes show an isolation problem on the HV battery.
Since clearing the codes, and having them re appear, tends to say that they are real. I also think that isolation failure disables the 12 volt charger or at least messes up the 12 volt charging.
There have been a few Isolation problems on here, and Dala made a video on how to confirm if it is in the battery pack.
Do a search for Dala's video and confirm if the problem is in the pack.
True isolation issues are not going to be easy to resolve, and may require removing the HV traction battery.
Sorry for the bad news.
