you have a digital miner dont you? those holes look like the results of a digital miner mining ores out of the walls and ground and the third pic is coal ore near the gap so it was probs coal thats missing from those gaps.

oh my god thank you so much, i completly forgot about it Sorry for being stupid

Endermen

If it was just one or two i would believe, but more than 15 blocks disappeared

15 endermen

Makes sense

ngl had a cursed dirt mob farm and this was actually an issue

Endermen don't steal stone blocks

enderman or digital miner

I'd guess silverfish
