What wildlife would do this

That is a puzzle. I think your entanglement idea is a good one. But as to who or what. I have no idea. Can you put a trail cam up ?

Could do but haven't got one. If it happens again I can borrow one from the Library of Things like we did last year when we had a rabbit invasion.  Looking at the gap where the plant was there's a smal depression like a cat might have scratched then been frightened away and took the bean plant with it. Anyway all is well this morning,  no further disturbance.
