The world is not loaded, neither your own, nor by invitation

Hello. My child has problems accessing any world in the game. Cannot enter either his own world or by invitation. The download hangs and does not move anywhere. It started with version 1.17.04. We tried to clear the cache, deleted and reinstalled the game, nothing helps. We play through wi-fi, the network catches well. Its tag is in the game MasterMirror143. I would like to know what is the reason and how can I fix it?
