You have outdated (versions of) addons (or potentially other mods): dreams n desires, extended gears, vintage improvements
Do note that not all addons have updated to support 6.0 yet; dreams n desires is such a mod on 1.20.1, vintage improvements is another but does have a fork you could theoretically compile and build https://github.com/SSWTLZZ69/Create-Vintage-Improvements/tree/1.20.1

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.
