Okay so one day I went on MCPE and it turned into a black screen and took 5 minutes to load. I believe this is happening because I previously downloaded a MC map. I went into File Explorer and tried to find the map file but it wasnt there, so idk how I can fix this problem. Could I delete the com.mojang file, uninstall MCPE, then reinstall it to fix this issue? Please answer soon cause I'm desperate to fix this.
