Managed to resolve on my own. I replaced the drivers from MatterControl with the drivers from Creality's website: https://www.th3dstudio.com/knowledgebase/creality-printer-drivers-all-models/ If you are encountering this issue, you'll need to download 'FTDI F232R Windows Driver" from the link above, then update the driver manually. For anyone who doesn't know how to do this, this guide can be used, but make sure to replace the drivers specified (C:\Program Files (x86)\MatterControl\StaticData\Drivers) with the ones from the Creality link above. Device Manager should report a "USB to Serial" adapter instead of "FTDI". https://matterhackers.helpscoutdocs.com/article/22-installing-drivers
