Mincraft Bedrock Edition on Windows 10 64Bit -

Recently, upon the Minecraft Bedrock version update, the Minecraft install no longer starts up properly.  All I get now upon startup is the Game Loading screen, after that completes, the minecraft 3D-looking graphics displays, but it is all blocks, in red, lava and turquoise, and the minecraft game sound.  However, nothing else is displayed, nothing is selectable and there is a game soundin the background.  We have tried reloading windows, reloading the game and reloading the graphics drivers - Intel and AMD; without luck.  Even upon re-installing, I believe I paid again for the game.  This is very frustrating that this is NO LONGER starting up.  Please help to fix this!
