This article isn't giddy about the discrepancy. https://www.forbes.com/sites/startswithabang /2021/04/08/why-you-should-doubt-new-physics-from-the-latest-muon -g-2-results/?sh=2317145b6c4b
It seems there are two ways to calculate g-2. The older way is a more indirect method that uses other experimental results. The newer way is completely theory driven and gives results which are closer to the Fermi Lab results.
