Maybe this URL makes it seem more legit than it is, but the linked article below has a "2.5" version of events that proposed that samples taken from a group with who'd been infected by a coronavirus from bats may have been released accidentally. In other words that the lab was the point of release, but that they didn't construct or alter the virus as it already had adapted to humans in an earlier time.
I've done some separate reading that this is a legitimate way that viruses can adapt to a new species, but I don't have any background to evaluate the argument much beyond face value.
Some of the adjacent comments shed some doubt there as it sounds like bats aren't a plausible source because of the spike protein genetics.
