keyboard blackwindow esc f1...f10 not working

Hey, @firstFeldgrauCITRINE849!

Does it make any difference when the Razer Synapse software is temporarily disabled? You can also try to reinstall your keyboards drivers by following the steps below:

1. Press Windows + S on your device to open the Search bar.
2. Type in “Device Manager” and hit Enter.
3. Go to "Keyboards" or "Human Interface Device".
4. Right-click on the Razer BlackWidow and select Uninstall device.
5. Restart your computer to completely uninstall the drivers.

The drivers will automatically reinstall after your computer restarts.If that didn’t do the trick, then shoot me a PM along with your device’s serial number so I can validate it and check for other workarounds.
