.mcworld file cannot be imported to Minecraft

first notice

so I was cloning my phone to my new phone with android 11 software, but app data can't be imported, so I manually archive my worlds and convert it to ".mcworld" file, but when I was opening the file following with (automatically) opening Minecraft (for Android) the notification bar said: "world import started" then "world import failed"

what's the problem could possibly be

Then I tried to manually unzip and move the folder to "android/data/com.mojang.minecraftpe/files/games/com.mojang/minecraftWolrd" but.... The access to the "android/data" folder was denied...... After doing some research, turned out that android 11, doesn't give you access to "android/data" folder.... The only application that could access it I've known so far is "google file"..... Then I tried to move my worlds folder to the Minecraft's data folder and then google file doesn't let me move my worlds, (even though I could still copy or move some items from the "android/data" folder)............ So I think that is the major problem

Please fix it, I need my favorite worlds come back to me in my new better device

That's it
