Anytime I load up Minecraft my A button will not work.   If I Uninstall and reinstall the game Sometimes it will fix the issue, however it doesn't always work.   Doing this every time I want to play is not a solution though. 

I'm playing on an Xbox X console.  My controller is brand new an has worked with everything else on my console.  Ithas been updated. 

Thank you for checking out this issue.  Minecraft has been the best stress relief for me after a very long day and I would love to get back to playing soon.
