      abstract     = {Measurements of the p$_T$-dependent flow vector
                      fluctuations in Pb–Pb collisions at $\sqrt{s_{NN}}$ =
                      5.02TeV using azimuthal correlations with the ALICE
                      experiment at the Large Hadron Collider are presented. A
                      four-particle correlation approach [ALICE Collaboration,
                      Phys. Rev. C 107, L051901 (2023)] is used to quantify the
                      effects of flow angle and magnitude fluctuations separately.
                      This paper extends previous studies to additional centrality
                      intervals and provides measurements of the p$_T$-dependent
                      flow vector fluctuations at $\sqrt{s_{NN}}$ = 5.02TeV with
                      two-particle correlations. Significant p$_T$-dependent
                      fluctuations of the V⃗$_2$ flow vector in Pb–Pb
                      collisions are found across different centrality ranges,
                      with the largest fluctuations of up to ∼15\% being present
                      in the 5\% most central collisions. In parallel, no evidence
                      of significant p$_T$-dependent fluctuations of V⃗$_3$ or
                      V⃗$_4$ is found. Additionally, evidence of flow angle and
                      magnitude fluctuations is observed with more than 5σ
                      significance in central collisions. These observations in
                      Pb–Pb collisions indicate where the classical picture of
                      hydrodynamic modeling with a common symmetry plane breaks
                      down. This has implications for hard probes at high p$_T$,
                      which might be biased by p$_T$-dependent flow angle
                      fluctuations of at least 23\% in central collisions. Given
                      the presented results, existing theoretical models should be
                      reexamined to improve our understanding of initial
                      conditions, quark–gluon plasma properties, and the dynamic
                      evolution of the created system.},
