On the contrary. She suggests adhering to it. The notion of whether a theory is elegant or beautiful is exogenous to the question if it describes nature, hence should be cut by the razor. In technical terms, there is no need for a prior on theory space: https://arxiv.org/abs/1801.02176 --- 5.2 Occam’s Razor A probability distribution from which to calculate the most likely choice of parameter adds unnecessary structure to the theory and is thus in conflict with the dictum of simplicity. We could have chosen a parameter and be done with it. The probability distribution and all the not-observed…

None of what you say contradicts that HEP Theory is in a crisis. That word was thrown around before the LHC confirmed the Standard Model, it's become more acute since. The crisis is that the foundational ideas about how to make progress in physics: Elegance, beauty, naturalness, symmetries... are not yeilding any insights on the questions you raise. And yet CERN still argues that HL-LHC is important for detecting supersymmetry in their press release today. The technical core of Hossenfelders argument is here: https://arxiv.org/abs/1801.02176
