Unable to lvl up

So i started a new region. But each time i try to lvl up a toon there, my game close. So i can’t do shit and the support only give me the answer “we’ll take it to the team, we dunno when it will be fixed” so since it make the game totally unplayable, i wanted to know if someone already experienced it and have find a solution? I already tried to delete the game but nothing change.

Lmao yeah its a solution, but i would love to have one who allow me to play ^^
