  We analyze the recent hints of lepton flavor universality violation in both
charged-current and neutral-current rare decays of $B$-mesons in an $R$-parity
violating supersymmetric scenario. Motivated by simplicity and minimality, we
had earlier postulated the third-generation superpartners to be the lightest
(calling the scenario "RPV3") and explicitly showed that it preserves gauge
coupling unification and of course has the usual attribute of naturally
addressing the Higgs radiative stability. Here we show that both $R_{D^{(*)}}$
and $R_{K^{(*)}}$ flavor anomalies can be addressed in this RPV3 framework.
Interestingly, this scenario may also be able to accommodate two other
seemingly disparate anomalies, namely, the longstanding discrepancy in the muon
$(g-2)$, as well as the recent anomalous upgoing ultra-high energy ANITA
events. Based on symmetry arguments, we consider three different benchmark
points for the relevant RPV3 couplings and carve out the regions of parameter
space where all (or some) of these anomalies can be simultaneously explained.
We find it remarkable that such overlap regions exist, given the plethora of
precision low-energy and high-energy experimental constraints on the minimal
model parameter space. The third-generation superpartners needed in this
theoretical construction are all in the 1-10 TeV range, accessible at the LHC
and/or next-generation hadron collider. We also discuss some testable
predictions for the lepton-flavor-violating decays of the tau-lepton and
$B$-mesons for the current and future $B$-physics experiments, such as LHCb and
Belle II. Complementary tests of the flavor anomalies in the high-$p_T$ regime
in collider experiments such as the LHC are also discussed.
