My Minecraft will not load.

Recently I tried to get on Minecraft bedrock but it was not working out and will not load. I had tried to uninstall and reinstall multiple times, Delete the game and re-download it. I emailed Minecraft and tried every method and I still can not get my Minecraft to load. The screen will either stay red, flash black and red, or have a glitch issue (the attachments). I don't know what to do anymore I did every research and nothing compares to this one.
