Device discovery in Razer Synapse 3

I have these Razer devices: - Razer Huntsman Elite (Keyboard ) - Razer Deathadder Essential (Mouse ) - Razer Nari (Headphones ) ______ Synapse 3 stopped showing them in the device list. I re-installed it. For some time, the program did not want to be installed and run at all. Tried to reinstall 3 times until I tried to uninstall it via Windows apps (10). There appeared a window for installing additional components. I installed additional components. After that, the program started working again, but the device was never found. It used to be all right, but now it's not. What should I do now?
