Si tu utilise des mod, tu vas devoie mettre a jour BepinEX (recente version a ete mise a jour il y a environ 14 heures selon la page sur Thunderstore).
J'ai eu la meme difficulter, et c'est la premiere chose que j'ai verifier :)

If using mods, you need to update to the latest BepInEX (updated about 14 hours ago on the Thunderstore web page).
Had the same problem, and the update took care of it.
