In 2022, analysis of the old CDF experiment at Fermilab measured the mass of the W boson to be in 7-sigma tension with the Standard Model prediction, also disagreeing with CMS's measurement. https://www.science.org/doi/10.1126/science.abk1781 https://en.wikipedia.org/wiki/W_and_Z_bosons#2022_unexpected_measurement_of_W_boson_mass
Other experiments (almost certainly ATLAS at the LHC) will need to confirm this before the physics community is sure of this.
