"waiting for ZeroTier system service"

hi, i’ve been trying to open the desktop ui for zerotier for hours now. I have the latest version 1.8.4), the service is running, but when i click on the tray icon i got only 1 option : quit zerotier ui. The other option is greyed out so i can’t click it and it’s saying “waiting for ZeroTier system service”.

I’ve checked my firewall and all the rules are accepted and the ports are ok, nothing is blocking anything. i’m clueless at this point so i need help please. ty
