I've over 150 plugins working at once, Kaus' and the plugins listed in the OP among them. Make sure your other plugins are compatible with one another, and also make sure to have Kaus' plugins near the bottom (and in the correct order) of your plugin list, positioning of plugins is vital because it ensures proper run order. Try moving Kaus' plugins below the other ones, or perhaps even above. This is a surprisingly very compatible plugin, make sure you have the files set up correctly as well to avoid other errors. Also make sure you are updated to the latest version of RPG Maker MV!
