h320M tablet pen not working.

So we bought the tablet off Amazon and it arrived today. We followed the instructions on the huion website for downloading driver, whitelisting the app etc. It says device connected, however we have a few problems once it's plugged in. 1. The mouse doesn't work at all. The cursor flies off to the side of the screen and the mouse won't move it. 2. The pen doesn't work either. It doesn't do anything. We have tried all the trouble shooting on the website. Uninstalling driver and reinstalling it, changing USB slots, restarting the computer. No matter what we do, we can't get it to work. If we plug the tablet in without the driver, the pen still doesn't work. With both the mouse and the pen not working when the tablet is plugged in, we can't do anything. For reference, we are using a Mac with Monterey. Any help appreciated!
