I'm just going to type exactly what forge told me when I failed to load:

BasicEndOres (beo) has failed to load correctly
Javanlang.NoSuchFeildError: Class
Net.minecraft.core.registries.Registries does not have member feild 'net.minecraft.resourses.ResourceKey f_279569_'

Thanks for reporting. This was identified last night and is fixed with version 5.0.2.
