I downloaded a map from mcpedl, extracted the world from the zip and I put it in the worlds folder. After that I loaded up MCPE so I could check out the map and I entered the map and soon after I tapped to enter the map, it crashed. Several attempts passed and I went to the map setting and I saw nothing wrong but when I scrolled down I saw the map was made in old type of generated map so u scrolled bit down and found the "convert to infinite" option. I did that and it crashed. I thought it was a some kind of error or I had no space so I uninstalled some apps thinking it would work but no it kept on crashing but when I go to other worlds I already have that are HEAVIER (the one I'm trying to convert is 21,31Mb and one of my worlds I have is double of that) it loads my world. Now I'm not sure if it's MCPE that can't handle me trying to convert the world or if it's not possible now or the world is corrupted to not be able to convert to infinite
