I updated the plugin to work with version 1.16.X. I apologize for not keeping up to date with the last few versions. It seems that the crafting bench isn't seeing any new updates lately so I think I should just implement a fail-safe so that if a future update (lets say v1_17_R1) doesn't exist or have support it tries to use the latest version and hope it works, if it doesn't then an actual update would be required.
