I doubt they are actually related but it’s something I read presumably because:
“Wuhan Branch of the CAS.[4] Located in Jiangxia District, Wuhan, Hubei, it was founded in 1956 and opened mainland China's first biosafety level 4 (BSL-4) laboratory[5] in 2018.” https://en.wikipedia.org/wiki/Wuhan_Institute_of_Virology
There was also a separate BSL-2 facility that moved right before the outbreak which also got news coverage due to the timing. But I think that was more confusion as they shouldn’t be working on coronaviruses in a BSL-2 facility.
They in fact were working on coronaviruses in a BSL-2 facility, which is another thing that helps make the lab leak hypothesis more plausible. E.g. from Vanity Fair:
Baric testified that he had specifically warned Shi Zhengli that the WIV’s critical coronavirus research was being conducted in labs with insufficient biosafety protections. When he urged her to move the work to a more secure biosafety level 3 (BSL-3) lab, he testified that she did not heed his recommendation. Because the WIV continued to perform coronavirus research at what he considers an inappropriately low biosafety level, Baric said of a laboratory accident, “You can’t rule that out…. You just can’t.”
In 2004, nine people were infected with Sars and one person died after two researchers were separately exposed to the virus while working at the Chinese Institute of Virology in Beijing. In November 2019, just a month before the first confirmed case of Covid-19, more than 6,000 people in north-west China were infected with brucellosis, a bacterial disease with flu-like symptoms, after a leak at a vaccine plant.

The Chinese facility hosts one of no more than six BSL-4 labs in the world that had been conducting contentious “gain of function” research on bat-related pathogens before the pandemic, according to Richard Ebright, professor of chemical biology at Rutgers University [1]
Just given the above, the statistical likelihood of coincidence is so absurdly low it alone means there needs to be overwhelming evidence to the opposite to overcome it. At no point has this been the case.
