Turn Off Core Isolation
Search for Core isolation in your Windows Settings and then make sure that Memory integrity within it, is toggled off.

To find this section, search for dynamic lighting and you should see "Change lighting colors, brightness, and effects" appear.
Once you're there, make sure that "Use Dynamic Lighting on my devices" and "Compatible apps in the foreground always control lighting" are toggled off.
We turn this off because it's a background app that manages your RGB lighting which can conflict with your other programs that already do this.
