I'm having this problem kinda out of nowhere, about a week ago it was working perfectly.
So, whenever I open any Studio One native plugins or Vsti, the GUI lags very hard, making it extremely hard to actually tweek the settings. This only happens with the usser interface, actual audio is not having problems. And it's worth mentioning that I don't have a problem with any 3rd party plugins or VSTi.
I'm running Studio One Pro 4.6 in Windows 10 and I'm using a Ryzen 7 3700x as my CPU, 2x8 Gb of RAM at 3200Mhz and a RTX 2060 as my GPU.
I tried reinstalling and trying older versions but it doesn't seem to work.
