I’m not receiving any blocks I break

Ok so this problem sounds quite silly but it’s a real life problem right now and I’m very frustrated. After I updated my Minecraft I decided I wanted to play and needed to go mining I go about my business getting everything I need for my trip you know the basics and when I finally find a good cave I begin breaking blocks and NADA I don’t get anything I break at all no coal no cobble nothing. I tried switching pickaxes and that didn’t work and I also checked an older world to see if it was affected and it wasn’t so I tried copying the world and that didn’t work and I know you’re probably thinking just make another world but I grind my butt off on this world and I don’t wanna give it up SO HELP PLEASE!!
