Razer huntsman tournament edition - some keys aren't working

I have some trouble with my razer huntsman tournament edition. After not using my pc for about two weeks, after booting it up I noticed that my spacebar and ‘5’ key aren’t working. Also, some of the keys are shining in different colors they are suposed tobut razer synapse tells me that everything works as it should be. I tried cleaning my keyboard, reinstalling the software, installing new drivers and switching the usb port. The keyboard doesn’t work even on other devices but my second keyboard works fine on the same pc i had a problem with my razer one.
