Not sure what is causing the error, but it says ticking player. Try backing up your player.dat and delete it from the save so it creates a new one. Unfortunately if this works you will possibly loose all your research and will loose all your items along with some other stuff saved in your player.dat If you want you might be able to use an NBTEditor to remove the possibly effected item(s).
