Yes, my opinion is that virus came from a lab but was not intended as a bioweapon.
Scientists in the US and China have been doing gain-of-function research by combining features of naturally occurring coronaviruses. The idea of the work is to understand virus better, but the work involves developing dangerous strains that can infect humans. Here is one example with a lead author from the University of North Carolina and co-authors from a lab in Wuhan, China:

My opinion, is the COVID-19 is the result of an accidental release of a similar virus.
Work in Wuhan involving coronaviruses was no secret, and there are reports the US government actually spent $3.7 million to fund research that brought bat coronaviruses from remote parts of China back to Wuhan for laboratory study. Lab origin and natural origin are not mutually exclusive.
