Everything freezes

Whenever I mine diamonds my entire game freezes a bit after. I start mining after i got the diamonds and the blocks drop nothing. Animals and villagers freeze in place and when i hit them they dont get hurt. Chest, beds, crafting table etc. also freeze. i dont know if its the diamonds that froze my game or if its something else but i mined the same diamonds 3 times and it keeps freezing my game. I can move around though. Im using a few mods which work fine idk if that also causes the problem
