You have outdated (versions of) addons (or potentially other mods): northstar, design n decor, steam n rails
Do note that not all addons have updated to support 6.0/the latest version of 6.0 yet;

Make sure all your mods are updated to the latest version, and for addons check whether their changelog mentions that they now support 6.0; the internal changes are big enough that essentially any non-datapack addon will be broken if they haven’t.
I haven't checked mod compatibility beyond the mods I mentioned, you should do some level of investigation in that regard yourself.
