The measurement of lepton universality parameters $R_{K^{(*)}}$ was updatedby LHCb in December 2022, which indicated that the well-known anomalies inflavor-changing neutral current (FCNC) processes of B meson decays have fadedaway. However, does this mean that all new physics possibilities related to$b\to s\ell^+\ell^-$ have been excluded? We aim to answer this question in thiswork. The state-of-the-art effective Hamiltonian is adopted to describe $b \tos$ transition, while BSM (beyond the Standard Model) new physics effects areencoded in Wilson coefficients (WCs). Using around 200 observables in leptonicand semileptonic decays of B mesons and bottom baryons, measured by LHCb, CMS,ATLAS, Belle, and BaBar, we perform global fits of these Wilson coefficients infour different scenarios. In particular, lepton flavors in WCs are specified insome of the working scenarios. To see the change of new physics parameters, weuse both the data before and after the 2022 release of $R_{K^{(*)}}$ in twoseparate sets of fits. We find that in three of the four scenarios, $\DeltaC_9^\mu$ still has a deviation around or more than $4\sigma$ from the StandardModel. The lepton flavor in WCs is distinguishable for $\Delta C_{9}$ at the$1\sigma$ level, but at the $2\sigma$ level all the operators are flavoridentical. We demonstrate numerically that there is no chirality for muon typeof scalar operator and it is kept at the $1\sigma$ level for their electrontype dual ones, while chiral difference exists for $\mathcal{O}_{9}^\mu$ atleast at the $2\sigma$ level. Moreover, it can be deduced that the scalaroperators $\mathcal{O}_{S,P}^{(')\mu}$ become null if new physics emerges interms of SMEFT (Standard Model Effective Field Theory) up to dimension-6.
