I guess the SISL2 cranks are known to do this, carry a special two year warranty as a result, and of course mine is 7 years old so that doesn't mean squat. Bike parts are, of course, out of stock everywhere because 2022 is a joy just like 2020 and 2021. Grab a conversion BB for either Shimano or SRAM cranks. https://wheelsmfg.com/bottom-brackets.html?cat=900 I know Shimano has some Tiagra, Ultegra, and Dura-Ace cranks in stock in their North American warehouses. SRAM should have some stuff too, but I can only check their Canadian distributors and not the US ones.
