No, from the abstract of the paper "The orbital period, 185.6 days, is longer than that of any known stellar mass black hole binary. [...] How the system formed is uncertain. Common envelope evolution can only produce the system's wide orbit under extreme and likely unphysical assumptions"

See section 8.4 for details: https://arxiv.org/abs/2209.06833 But basically the idea is that they are assumed to have interacted in the past (based on the distance), and given that, all current models of such interactions would predict a very tight final orbit for the solar mass star.
