Bug

My elytra disappeared and it didn’t make sense because I died in my village and I wasn’t even far from my village when it happened, after I was killed by a pilliger, I didn’t see it again, and this was after I picked up my loots. It disappeared on me and I can’t find it and also, I can’t mine anything at all. I was trying to pick up dirt and nothing was being picked up. I don’t know what’s going on but I want my elytra back and I can’t mine anything at all.
