Game freezes whenever game mode or difficulty is changed

Every time I try and change the gamemode or game difficulty in the settings menu the game soft freezes. By soft freeze I mean I can still tap on the pop ups but I cant exit or do anything else unless I reset. This also happens when creating a new world. This bug is one of the worst right now and because of It I cant create any worlds in creative.

Edit: April 18th
This bug still exists. I would like the mods for reopening this. It still happens in 1.0.6 and is getting progressively more annoying. I had to download someone else's world just to /fill it to make it superflat because creating any superflat world is impossible.

To also add, very rarely this bug will not occur for me. This has only happened 3 times, all of those times its when im changing the difficulty of a creative world. No other time has this bug not happened. I am still not using any resource packs or mods. I am using the Classic UI profile but I have tested it, and it also occurs on the Pocket UI Profile. (Note that, yes I know the difficulty can be changed with commands. I forget that alot.)
