I'm confused, do you mean the animal origin had no evidence either, but was favoured? But not having evidence for 5 years suddenly makes the other theory favoured instead?
So basically neither had real evidence, but one was favoured?

Animal origin still seems more likely to me, but less than 5 years ago, since we have a missing link one would expect to see.
It does favor an accidental lab leak over a targeted weaponization and release, but it doesn't contradict a lab origin.
There was no evidence for a zoonotic origin other than it was possible.
There was little evidence for a lab leak other than it was possible, but at least there was some.
