If you have an app that can view files that are stored on your device, then I recommend that you go to the files app and go to the Minecraft folder. If there is something missing from the Minecraft folder that SHOULD be in the Minecraft folder, then this also may cause other problems with your Minecraft game.
Iโve only been playing Minecraft for 3 years now. ๐
I have never heard of dispensing items onto mobs in Minecraft before, but I still do wish I could help! ๐
If you add a Minecraft world into a realm and the Minecraft world is already corrupting, then adding a corrupted world into realms will probably stuff up your whole device (and Minecraft).
But if you see that you do have enough storage on your device for all of the Minecraft folders, then try checking your device for hardware issues.
Maybe try checking how much storage your device has left? If there is not enough storage left for all of the Minecraft folders, then you will have to get a USB or a hard drive to get more storage. Or you can make some more room for all of the Minecraft folders by deleting things off your device that you donโt need to be on your device anymore. Or you can upgrade your deviceโs storage plan or just get a new device. NOTE: Getting a new device and signing in to it even with a Microsoft account, all of the worlds on your old device will not be able to be played ever again. Also, if you delete the Minecraft or the files app, all of your Minecraft worlds and skins will be lost. (But your skins and marketplace pack will NOT be lost if you sign in and then save them to your Microsoft account and then sign in to your Microsoft account on another device. This should help (I hope!) ๐
If you have File Explorer or some other kind of app that can view files, try looking at those files. If something is missing that SHOULD be in the Minecraft file, then something is definitely wrong.
If you have way too many worlds, then this may cause the problem (too many worlds will cause the problem). Even though I have 219 worlds, everything in my Minecraft seems to work fine. My device platform is Minecraft PE on iOS with the Minecraft version as 1.14.60 I really hope this helps ๐
If you are playing Minecraft PE, then you will not be able to hear the jukebox sound at all (even if your volume level is 100%).
