My game is throwing errors on launch when certain CGC plugins are enabled. I'm using RPG Maker MZ. I recently downloaded the latest version of the plugins and copied them to the preexisting (as in, made with an earlier version) project. I've been bashing my head against a brick wall trying to figure out what's causing the problem, My amateur investigation reveals that three plugins are throwing the errors.

The game launches with these three plugins disabled. However, attempts to show the cards on screen produces another error describing something "undefined."

When I enable any of the three plugins out of the ones I have to disable to get the game to run, I get an error on launch:



I'm certain there's some problem with how my game is presently configured but I don't know what it is. I'm also certain that it could be resolved by starting the project over with a template from the latest version, but I would rather not do that, if possible. Any help would be appreciated!
