Just a heads up for everyone.

Windows 11 updated my COM3 driver to wch.cn - Ports - 3.8.2023.2, causing Prismatik to be unable to control the LED strip I was using.

Everything is working again after going to Device Manager > Ports (COM & LPT) > USB-SERIAL CH340 properties > Driver > Roll Back Driver

Hope this helps anyone who is having trouble after recent updates.

I agree, when downgrading the driver to 3.5.2019.1 everything is back to normal.
