It looks like it was done a while ago. I would guess during the early 2000's real estate boom. There were a lot of inexperienced people renovating homes.
You can tell it's old by how smooth the concrete is where it was knocked out. Concrete will have sharp edges on new defects or active defects.
I wouldn't imagine too much of an issue with it. The joists above are singels and the holes between them, so there are not walls or load supports above. Probably open floor above. Again, the smooth concrete indicates that there's no movement of the foundation. The sill plate wood is also in excellent condition. No cracking or loss of wood.
It looks way worse than it is. You'd be better off spending the money to encapsulating the crawlspace rather than repairing this issue.
