Suggestion / Bug Platform

So i download the launcher, and use the latest snapshot verions of labymod on 1.21 and decide to add some fabric mods. After select some mods i start the game up, but mods aren't loaded. I check the logs and found this:

[AddonPreparer] The addon "labyfabric" is unloaded because the "net.labymod.addons.labyfabric.launch.LabyFabricEntrypoint" entrypoint threw an exception!
