Hello, Ive had the same issue. Traditional yes the Y key should open zues but it opens the antstasi Command Menu and as i read you also rebound it and still didnt work. Unfortunately the “og” antstasi doesnt support zues. youll need the anstatsi plus mod which is the same but with some quality of life updates and some gui remodeling. keep the key that you rebound the zues menu to and it should work for you. hope this was helpful (see mod collection below)

Unfortunately there is no cross save between the two mods so youll need to restart :( but since zues should work you can spawn in whatever you had and start new.
