razer blackshark V2 hyperspeed setting window goes blank when trying to change things

when i was on synapse 3 it was working great, all THX surround audio options on supported games worked perfectly, but when updating to synapse 4, when i try changing setting or just activate the THX surround, they are not changing anything, the audio stays the same, even worst is when i import my personal setting, the page for my headset just goes blank, i tried to repare and even reinstal synapse, but nothing happens, can someone tell me if there is a fix or do i just wait for a fix ?
