Describe the bug
When loading Spectrum and its dependencies with Sinytra Connector the game crashes on launch

Mod version
compiled both the latest github versions for spectrum (1.7.5) and revelationary (1.3.6)

Crash Report
latest.log
https://mclo.gs/5niimxQ

in the prism log it mentions §6cardinal-components-world§r missing as well, right after a bunch of mixin errors

Caused by: org.spongepowered.asm.mixin.injection.throwables.InjectionError: Critical injection failure: Constant modifier method getActualReachDistance(DLnet/minecraft/world/level/Level;Lnet/minecraft/world/entity/player/Player;)D in mixins.reach-entity-attributes.json:ItemMixin from mod reach_entity_attributes failed injection check, (0/4) succeeded.

The lib Reach Entity Attributes has a mixin issue somehow.
With 1.20.2 that lib will be obsolete, since vanilla will have that functionality, but it would still be nice if it worked with Sinytra on 1.20.1. Best to report it to them.

Running fine for me on 1.20.1, using Connector Extras prevents a startup crash. Without it the crash will happen though.

Sounds like adding Connector Extras does the trick
