The Anthropic principle idea that this universe's physical properties can't vary much and produce carbon/hydrogen/oxygen (CHO) based life on the surface of planets is probably not correct and was just popularized many decades ago when the understanding of nuclear physics was not as complete as it is now. The possible paths to a CHO universe with acceptable planet surface conditions were not well explored. From the linked article: "Suppose the fine structure constant were in fact 10% different — enough to prevent stellar fusion from producing carbon." This is an old idea and is probably false (I am not an astro/nuclear physicist) but the author of this in-depth paper is[1]. Fred Adams is at the Physics and Astronomy departments at the University of Michigan and in this 2019 paper[1], with over 500 references, states the fine structure constant can vary by 4 decades/orders of magnitude (decade=log10(max value/min value)). See table two on page 140 for that range and ranges of some other fundamental values. The most constrained value ranges still vary by an order of magnitude (down quark mass and the up-down quark mass difference).
