Same issue but it goes deeper. Since Windows updated to 2004, f.lux has had a habit of switching itself off intermittently when I open notifications, the settings app, and other Windows accessories. When I start my laptop it's active, and within a few seconds it switches off and I can only turn it back on by clicking on my taskbar, and if I'm active for a long time, it'll sometimes switch off again. Night light mode is off and I use f.lux as my default blue light filter at 4000K during the day, so it's incredibly noticeable.
