Ps4 Minecraft: game hangs up and no way to get into my world?

I downloaded Minecraft and gambled. Myself and my friend in one world surely have more than 2 or 3 days of game time… Today my brother simply switched off my PS4 while I was ingame. Then switched on again, but I can no longer enter the one world. My 2nd world that I still worked. I have already switched off the PS4 several times, closed Minecraft and also deleted and reinstalled Minecraft. Still it doesn't work. Do you have any idea what I can do?

Since you had not saved the world and your brother simply switched off the ps4, the data for this world have probably been lost. My condolences😶🌫️
