Yes, it was a cable problem. Sorry for the delay.
If this can help anyone, all USB-C cables doesn’t work with this tablet because the connection port is too deep and some of them doesn’t make propper contact. I bought a Choetech cable and this works fine.
But this tablet is a mess, I don’t know if the new ones are better but this one restarts automatically by itself and the storage is very limited and pretty difficult to modificate because the SD doesn’t work
