There can be various reasons that cause the keyboard to stop working, unfortunately we can not precise what seems to have been an issue with yours.
There can be different causes here but the most probable is the Power management setting. As the system disconnects some peripherals in order to save energy. This might be the case with your Windows 10 OP.
You can try turning off power saving options, this power-saving option in Windows allows the computer to disconnect the idle devices to conserve power. However, this can also cause issues with USB devices.
If disconnect happens again, try disabling the option and check for any improvements.
- Press “Windows Key + R” to open Run.
- Type devmgmt.msc and click OK to open the Device Manager.
- Click to expand the Keyboard section.
- Right-click on “HID Keyboard Device” and select “Properties”.
- In the Properties window, click the Power Management
- Uncheck “Allow the computer to turn off the device to save power” option.
- Click OK to save the changes.
- Disconnect your keyboard and plug it back in.
- Also, try updating the drivers and OP from here https://fnatic.com/gear/op.
Sometimes a USB port can just stop working when you upgrade to a new version of Windows. Usually it’s because of a driver problem. You should always check for this problem first. Fortunately it’s easy to test: simply unplug the keyboard from the USB port and plug in another USB device.
The keyboard reset is always the option for fixing the problem, with the keyboard plugged in:
1. Locate the reset hole on the underside of the keyboard (below the keyboard feet)
2. Use a pin and hold in the hole for 10+ seconds.
3. Observe the keyboard RGB flashing, and wait for the reset to complete.
