If you have had minecraft for playstation 4 since before it was changed to bedrock edition in the 1.15 "Busy Bees" update, You got this "Editions" button, that lets you go back to the original playstation 4 edition (still stuck on the 1.14 "Village and Pillage" update). However, whenever I tried this in the last two-three weeks, the game instantly freezes. After that, I am unable to do anything in-game. the only thing I can do is exit the game, close it, and reopen it. This keeps happening, and I am unable to go back to this old version. I hope I have provided You with enough information on this topic.
