What on earth is eating my stems

I have some sort of bug eating the stems of my kale, beans and squashes. At first I thought it was squash vine borer but it wasn’t making holes and the dead squashes had no maggots in them. Then my kale and beans started receiving the same damage, getting the portion of the main stem that’s underground chewed off. I have also ruled out cutworm as the damage is below the soil line and it looks like a tiny beaver chewed through it whereas cutworm lops the whole thing off clean a centimetre or so above the soil line. Has anyone had this? I am perplexed

That looks like possible snail or slug damage. Do you have any examples that are newer (as in don't have all the brown necrotic tissue around the wound)?

Interesting, these are in newly built raised beds filled half with arborist wood chips and logs so they drain well (a little too well really) so I didn’t suspect slugs and snails. I very well might have another picture for you tomorrow haha. Thank you for your reply!
