When running on PaperMC ver1.16.4-416, the following error occurred and the plugin did not work.
It worked with GeyserSkinManagerVer1.6.
[10:13:54 ERROR]: Error occurred while enabling GeyserSkinManager v1.7 (Is it up to date?)
java.lang.NoSuchMethodError: 'void org.yaml.snakeyaml.parser.ParserImpl.(org.yaml.snakeyaml.reader.StreamReader, org.yaml.snakeyaml.LoaderOptions)'
