lose worlds

Hello, so I want to talk about a bug that is making me very angry, After the new official update 1.18.2 I'm having serious problems regarding worlds, today my friend and I created a world without any application just the default game we opened discord
and we got on a call, we played for 3 hours and 50 minutes, but his cell phone was already downloading and so was mine and I closed the world and would send it to him so he could create a realms so I opened it My file manager went into the Android folder and all the files were gone, there were no behavior packages, textures, nothing, I opened my game again and the worlds were gone, gone... All me And my friend, we built such a beautiful underground base, we even made a waterfall and losing it is very sad because it was difficult to find the place, it was difficult to get land to change the floor, wait More than 10 minutes for the stones to heat up, more than every time I log out and log in my Microsoft account is disconnected I only ask for one thing fix this me and my friend gave it our all to build everything
